Understanding Email Deliverability
Ever sent an email campaign and wondered why so few people opened it? Or noticed some messages go straight to the promotions tab while others make it to the primary inbox?
Getting your emails in front of recipients is harder than it seems. That’s where email deliverability comes in.
Email deliverability refers to the rate at which your messages successfully arrive in your subscribers’ inboxes. It’s one of the most critical factors determining the success of any email marketing effort.
But what exactly impacts deliverability, and why does it matter so much? Let’s break it down.
What is Email Deliverability?
At its core, deliverability is about your emails getting to the right inbox at the right time.
It’s easy to assume that when you hit send, your message will instantly appear for all recipients. Unfortunately, that’s not quite how it works.
There are several potential hurdles between you and your subscribers’ inboxes:
- Spam filters – Both email providers like Gmail and organizations use filters to detect spam and dangerous emails. You need to avoid these to prevent deliverability issues.
- Authentication protocols – SPF, DKIM, and DMARC authenticate you as a legitimate sender. Without proper configuration, your mail may be flagged as untrusted.
- ISP throttling – Internet service providers can throttle or block servers with bad reputations to protect customers from spam.
- Engagement factors – Low open and click rates signal recipients aren’t interested. This reduces future deliverability.
Deliverability refers to navigating these and other obstacles to ensure your email arrives in inboxes reliably.
Why Email Deliverability Matters
Deliverability directly impacts your ability to connect with customers and drive results through email. Here are some of the factors it affects:
- Open and click rates – Your open and click-through rates depend entirely on recipients actually receiving your message. Higher deliverability means more opens.
- Conversions and revenue – Emails that never reach subscribers can’t generate sales. Improving deliverability directly translates to your bottom line.
- Brand reputation – Landing in the promotions tab or spam folder reflects poorly on your brand. Good deliverability builds trust and loyalty.
- Marketing costs – When deliverability suffers, you must send more emails to reach fewer people. This increases your costs.
- Email marketing ROI – With so many factors at stake, poor deliverability drastically reduces your return on investment from email campaigns.
Simply put, deliverability is the key to successful email marketing. That’s why monitoring and optimizing it is so critical.
Measuring Email Deliverability
The first step is tracking deliverability accurately. While not a perfect science, there are a few key metrics that provide visibility:
Open and Click-Through Rates
Open and click-through rates indicate your recipients are actually seeing and engaging with your emails. If these rates decline, it likely signals a deliverability problem.
However, open and click tracking tools don’t provide a full picture, since they only record subscribers who interacted with received emails. You can’t know if messages you sent never arrived.
Bounce Rates
A bounce occurs when an email fails to reach the recipient’s inbox and gets returned to the sender. Hard bounces indicate permanent deliverability failures, while soft bounces are temporary blockages.
Monitoring your overall bounce rate reveals issues impacting deliverability. A high bounce rate means many emails aren’t making it through.
Inbox Placement Rates
Emails don’t just land in the primary inbox or bounce. Many end up filed away into other tabs like promotions or spam.
Analyzing inbox placement rates sheds light on whether your emails are reaching the primary inbox vs. getting filtered. Declining inbox rates signal deliverability problems.
Combining metrics helps paint a complete deliverability picture and identify areas for optimization. Focusing solely on open rates misses the bigger picture.
The key is tracking deliverability continuously over time. That’s the only way to diagnose issues before they drastically impact performance.
Now that you understand what deliverability entails and why it’s vital for email marketing success, let’s explore some of the key factors that influence it.
Key Factors That Impact Deliverability
Deliverability depends on several key factors working together seamlessly. When any part of the process breaks down, your emails suffer.
Let’s explore the core components that determine whether your messages reach the inbox or not.
Sender Reputation
Your domain and IP address’s reputation significantly influences deliverability.
Reputation refers to your ongoing sending patterns and engagement levels. High volumes of spam complaints or bounces damage your sender score.
Email providers maintain internal scoring systems and share data on senders. If you develop a poor reputation with one major player like Gmail, others will likely block you too.
Maintaining a pristine reputation ensures deliverability success. Here are some best practices:
- Keep your list clean by removing inactive subscribers and bounces promptly.
- Monitor spam complaints and investigate the causes.
- Warm up new IP addresses gradually.
- Avoid sudden spikes in sending volume.
- Use double opt-in subscription flows.
- Provide an easy one-click unsubscribe option.
- Ensure engaging, relevant content subscribers want.
With consistent good habits, your reputation will remain stellar across providers.
Email Authentication
Authentication protocols like SPF, DKIM, and DMARC verify your identity as a legitimate sender.
Without proper authentication, recipients may classify your emails as untrusted and divert them to the spam folder automatically.
SPF
Sender Policy Framework authenticates you by allowing only authorized sending servers.
An SPF record lists IPs approved to send email from your domain. Receivers check the record to confirm the originating IP.
If an unauthorized server attempts sending, SPF authentication fails, harming deliverability.
Common issues like permerrors from too many DNS lookups also cause SPF failures. Optimizing your SPF record is essential.
DKIM
DomainKeys Identified Mail adds a digital signature to outbound messages, validating the content integrity.
Your email includes an encrypted DKIM signature tied to your domain. Receivers decrypt and verify this signature to confirm the message is authorized and unmodified.
Any tampering would invalidate the signature, allowing receivers to detect compromised or spoofed emails.
DMARC
Domain-based Message Authentication, Reporting & Conformance builds on SPF and DKIM.
It instructs receivers what to do if either mechanism fails, such as rejecting or quarantining messages.
A DMARC record specifies your authentication policies and reporting preferences. This provides an added layer of protection beyond SPF and DKIM alone.
Implementing all three protocols is critical for deliverability and security. They work together to confirm every message’s authenticity.
Avoiding Spam Filters
Both individual email services and organizations rely on advanced spam filters to protect inboxes.
These filters analyze emails using complex algorithms and rules to catch unwanted messages. Even the most legitimate email can occasionally be flagged as spam.
There are several ways to avoid filters and ensure inbox delivery:
- Send consistently – Don’t just email someone once and disappear. Consistency indicates you’re a reliable sender.
- Avoid spam trigger words – Don’t use phrases commonly found in spam emails that will trigger filters.
- Personalize content – Generic, impersonal text resembles spam. Personalize every message.
- Use double opt-in subscription – Confirm subscriptions to prove subscribers want your emails.
- Limit images and links – These are common in spam emails. Use them sparingly and host images yourself.
- Watch your frequency – Avoid bombarding people with too many emails in a short time.
With mindful sending habits, your emails will safely bypass spam filters unscathed.
Email Content and Design
Even if emails technically get delivered, content and design impact whether recipients actually read and engage with them.
Optimizing these factors leads to higher open and click-through rates:
- Compelling subject – Get creative to make them open your email.
- Relevant, valuable content – Deliver on the subject line’s promise with great info.
- Clear calls-to-action – Provide obvious next steps to click.
- Mobile responsiveness – Over 50% of emails are opened on mobile. Mobile-friendly, easy-scanning layouts are a must.
- Fast load times – Don’t overload emails with big images or files that are slow to load.
- Readable fonts and colors – Avoid hard-to-read color combos and funky fonts.
- Testing for rendering – Ensure your emails look as intended on different devices and email clients.
With great content and design, your emails drive more clicks and conversions once delivered.
Subscriber Engagement
Recipient behavior also impacts deliverability in the long run. Low open and click rates signal subscribers aren’t interested.
When recipients don’t engage, providers may throttlex sending volume to them. This protects customers from unwanted emails.
You can boost engagement with:
- Targeted, personalized messaging
- Segmenting your list by interests
- Regularly refreshing content
- Testing subject lines
- Following up inactive subscribers
Deliverability depends on recipients actually wanting your emails. Keeping their interest is crucial for ongoing inbox placement.
By continually monitoring and optimizing all of these key factors, you can achieve email marketing success. But even when you do everything right, deliverability hurdles still pop up.
Common Deliverability Issues and Solutions
Despite your best efforts, deliverability problems inevitably occur. Here are some of the most common issues and how to address them:
Hard vs. Soft Bounces
Bounces occur when an email fails to reach the recipient’s inbox and gets returned to the sender.
Hard bounces indicate permanent deliverability failures. This usually results from an invalid or deactivated email address. These subscribers should be removed from your list.
Soft bounces are temporary blockages such as when a subscriber’s inbox is full. Retry sending to soft bounced addresses until you receive a hard bounce.
Monitoring bounce rates and types provides visibility into list health issues impacting deliverability. Promptly scrub hard bounces from your list.
Inbox Placement
Delivered emails can still end up filed away into tabs like promotions or spam instead of the primary inbox.
If your inbox placement rates decline, try these troubleshooting tips:
- Improve subject lines – Clear, compelling subjects avoid false spam hits.
- Increase personalization – The more personalized content is, the more legitimate it appears.
- Change the sender name – Sometimes the “from” name triggers filtering if it looks suspicious.
- Test rendering – Ensure emails render properly across different clients.
- Analyze spam test results – Use tools to test spam scores and optimize content.
With adjustments, you can regain your footing in the primary inbox.
SPF Permerrors and DNS Lookup Limits
SPF permerrors result when SPF records exceed the 10 DNS lookup limit. This leads to failed SPF authentication.
Here are some tips to overcome this:
- Consolidate multiple SPF records into one.
- Reduce unnecessary “include” mechanisms.
- Replace lookups with IP addresses when possible.
- Delete unused domain references.
Optimizing your SPF record avoids permerrors and improves authentication.
Slow Email Opens and Render Times
Sluggish email load times frustrate recipients. Quickly fixing display issues is crucial.
- Limit large images – Big image files bog down email loading. Use smaller files or link to images on a webpage instead.
- Minimize CSS – Scale back on unnecessary CSS formatting that can cause latency.
- Check web host uptime – A slow or overloaded web host hampers image loading speed.
With fast rendering, your emails make a great first impression on recipients.
Low Open and Click-Through Rates
If your open and click rates decline, there may be broader deliverability issues at play.
Try these troubleshooting tips:
- Improve subject lines – Rework subject lines that aren’t compelling enough to open.
- Increase personalization – Leverage merge tags and segments to target content.
- Refresh your content – Outdated information gets ignored. Share timely, relevant content.
- Double check your lists – Remove inactive subscribers and bogus email addresses dragging down your rates. Addressing lackluster engagement metrics restores deliverability strength.
By identifying and quickly resolving any deliverability hiccups, you can keep your email marketing program running smoothly.
Improving Deliverability With Warmup
Sending emails from a new domain or account is a high-risk delivery scenario.
Without an established sending reputation, new senders are unknown entities. Email providers tend to err on the side of caution and limit delivery until you demonstrate good habits over time.
This is where email warmup comes in – gradually building your sender reputation to improve deliverability.
What is Email Warmup?
Warmup refers to slowly ramping up the volume of emails sent from a new domain or account. The goal is to establish a reliable sending pattern before full-scale messaging.
Instead of blasting thousands of emails on day one, you send limited batches to a small group of recipients. As long as emails are engaged with and don’t bounce or get marked as spam, sending increments increase over time.
Within a few weeks or months, your domain earns a reputable sender score for excellent deliverability going forward.
How Does Warming Up Work?
There are two core aspects of proper email warmup:
1. Starting with small batch sizes
When warming up a new domain, begin by sending just 10-50 emails per day. Slowly scale up by an additional 50-100 emails as long as prior batches had good engagement and delivery.
2. Warming up over time
Take weeks or months to gradually work up to larger sending volumes. This proves you are committed to quality over quantity. If you rush the process and spike volumes too quickly, deliverability suffers.
The warmup period depends on your target email volume. For example:
- 1,000 emails per day may take 2-4 weeks to ramp up to.
- 10,000+ emails per day could take 8-12 weeks for full warmup.
Patience and discipline are vital – fought deliverability at first to reap the long-term benefits.
Benefits of Warming Up
Taking the time to warming up new domains or accounts gives:
- Improved inbox placement rates – Gradual warmup minimizes the risk of spam folder filtering.
- Increased open and click-through rates – Recipients are more likely to engage with and look forward to your emails after the warmup period.
- Lower bounce rates – Warmup lets you identify and remove undeliverable addresses early before impacting your sender score.
- Reduced hosting costs – Ramping up slowly is easier on your web hosting infrastructure and costs.
- Peace of mind – You can send confidently once your domain establishes a positive reputation.
Warmup is the key to ensuring your emails reliably reach the inbox and get opened.
Email Warmup Best Practices
Following proven warmup workflows is essential:
- Use dedicated IPs – Warm up each new IP address independently starting with low volumes.
- Verify email addresses – Confirm all addresses are valid and able to receive to minimize early bounces.
- Send consistently – Stick to daily schedule sending rather than large batch blasts.
- Create tailored content – Craft engaging messages recipients actually want to receive.
- Use double opt-in – Have recipients reconfirm their interest to ensure you’re not spamming.
- Monitor and adjust – Keep close tabs on engagement, delivery, and complaints. Tweak your approach over time.
With a thoughtful, compliant warmup routine, your sender reputation will flourish.

Monitoring and Analyzing Deliverability
Once your deliverability strategy is in place, the work has just begun. Ongoing monitoring and analysis are crucial for diagnosing issues and continuously optimizing performance.
Why Track Email Metrics?
Email marketing success depends on reliably reaching subscribers’ inboxes and driving engagement. Tracking key metrics makes it possible to:
- Identify problems early – Nip deliverability issues in the bud before they spiral.
- Figure out what’s working – Double down on tactics and campaigns getting results.
- Optimize areas needing improvement – Experiment and iterate to increase open rates, lower bounce rates, etc.
- Benchmark progress over time – Set deliverability goals and evaluate if you’re advancing.
You can only improve what you can measure. Consistent tracking provides the visibility needed to enhance email success.
Deliverability Metrics to Monitor
There are a handful of essential metrics that shed light on your email deliverability health:
Open and Click-Through Tracking
As discussed earlier, open and click-through rates help gauge recipient engagement.
Sudden significant drops in these metrics often indicate deliverability problems. However, high rates alone don’t paint the full picture.
Monitoring these metrics over the long haul reveals the impact of changes you make. Try altering subject lines, content formats, or schedules and track the effects on open and click rates.
Bounce Tracking
Keeping tabs on bounce rates and bounce types (hard vs. soft) provides immediate delivery diagnostics.
A sudden spike in bounces signals something is amiss. Review recent email content for issues. Cross-check bounced addresses against your list for errors.
Ahigh hard bounce rate overall requires list maintenance to remove invalid emails dragging down deliverability. Monitor this metric weekly.
Inbox Placement Monitoring
Don’t just track delivers—pay attention to inbox placement as well.
Seeing the percentage of emails landing in the primary inbox vs. other tabs identifies deliverability roadblocks.
If your primary inbox rate declines, tweak your content to avoid false spam detections. Testing emails against spam filters also helps.
Engagement Monitoring
Engagement metrics indicate how recipients interact with your emails beyond opens and clicks.
Replies, forwarded emails, link clicks, and social sharing all demonstrate higher levels of subscriber interest and trust.
Falling engagement levels signal your content may not resonate. Review recent email topics and test new formats to reinvigorate your audience.
Combining all of these data points creates a comprehensive picture of your deliverability health over time.
Benchmarking Your Email Deliverability
In addition to ongoing monitoring, regularly benchmarking your performance against targets and industry averages is crucial.
Benchmarks identify areas where you excel and gaps needing improvement.
Here are some examples of key performance benchmarks to establish:
Deliverability Rate
Industry Average: 90-95%
Target: Anything above 90%
**Bounce Rate **
Industry Average: 5-10%
Target: Less than 5%
Spam Complaint Rate
Industry Average: Less than 0.1%
Target: 0.05% or lower
Unsubscribe Rate
Industry Average: 0.2% or lower
Target: Under 0.1%
Open Rates

Auditing and Optimizing Deliverability
Once you have deliverability baselines established, the next phase is auditing and enhancement.
Comprehensive audits identify problem areas while optimization services provide solutions tailored to your program. Maintaining an optimized environment ensures maximized email success over the long haul.
Email Deliverability Audits
Audits systematically inspect your entire email program for vulnerabilities and deliverability blockers.
The goal is to surface any weaknesses impacting email placement, engagement, and performance. Think of it as your annual physical for overall domain health.
Here are key components of a deliverability audit:
1. Sender Reputation Review
Confirm your IP and domain reputations across major ISPs. A negative perception by even one major player jeopardizes future delivery.
2. Authentication Protocol Audit
Verify SPF, DKIM, and DMARC are properly implemented with no configuration issues. Flawed protocols undermine email security and deliverability.
3. Content Analysis
Examine email content, links, images, and attachments for factors potentially triggering spam filters. Identify any high-risk components.
4. Design and Rendering Test
Check rendering across major email clients and devices. Ensure your emails appear as intended everywhere.
5. Link Validation
Confirm all links work, lead to relevant content, and use SSL encryption. Broken links hurt engagement.
6. Spam Filter Testing
Run emails through spam detection tools to flag any problems. Tweak content to improve spam test scores.
7. Blacklist Screening
Verify your domain and IP addresses don’t appear on any global or local email blacklists. Listings severely reduce inbox placement.
8. Engagement Analysis
Assess audience interaction levels including open, click-through, and conversion rates. Falling engagement prompts a deeper dive.
9. Infrastructure Review
Inspect web and email hosting infrastructure for issues like slow load times, interruptions, or scalability limits affecting deliverability.
Covering all of these bases paints a comprehensive picture of optimization opportunities to pursue.
Testing and Addressing Deliverability Issues
The audit highlights priority issues to tackle first. Confirm the scope and cause of each problem before acting.
Common tests used to diagnose deliverability issues include:
Spam Filter Testing
Submit a sampling of recent emails to spam detection tools to quantify the severity of filter triggering content. Test email components individually to pinpoint problem areas.
**A/B Testing **
A/B test adjusted content, like different subject lines or email formats. The version scoring higher for deliverability performs better.
Placement Testing
Use tools showing your inbox placement rate for a domain with major ISPs. Declining placement exposes problems needing resolution.
Link Validation
Analyze links for issues like broken URLs, missing SSL encryption, or redirects to shady sites that may get emails marked as spam.
Rendering Tests
Confirm rendering works cross-device and avoid problems like clipped content or intrusive mobile popups harming inbox placement.
Discovering the root causes behind deliverability breakdowns points the way to targeted optimization efforts.
Optimizing Authentication Protocols
With audit findings for SPF, DKIM, and DMARC in hand, take steps to optimize authentication:
Adjust SPF
- Consolidate SPF records
- Reduce DNS lookups through flattening
- Delete unused references causing permerrors
Improve DKIM
- Use larger encryption keys
- Ensure proper TXT record formatting
- Fix misconfigured selector/domain values
Enhance DMARC
- Transition from monitor to reject/quarantine modes
- Require DKIM + SPF pass for alignment
- Boost spam detection with forensic reports
Proper configuration hardens email security and boosts inbox placement rates substantially.
Improving Sender Reputation
To overcome damaged sender reputation, focus on demonstrating stellar habits:
Lower Complaint Rates
- Remove subscribers who mark messages as spam
- Disable inactive or unengaged contacts
- Send more relevant content
Reduce Bounces
- Scrub bad addresses before sending
- Monitor soft bounces and reactivate once resolved
- Quickly remove hard bounces
Increase Engagement
- Write compelling subject lines
- Segment subscribers by interests
- Test message formats like plain text vs HTML
- Collect feedback through surveys
Good standing is built over consistent time through recipient actions. Patience and persistence pay off.
Email Content Analysis and Optimization
Carefully inspect content components jeopardizing deliverability surface during audits:
Subject Lines
Avoid spammy words like “free” or “limited time”. Test curiosity-sparking phrases to drive more opens.
Content
Scale back promotional language and hyperbole that raises spam suspicions. Prioritize valuable information recipients want.
Links
Shorten lengthy URLs with clean link shorteners. Host images yourself rather than linking externally.
Images
Shrink large image file sizes for faster loading. Replace product images not adding value.
Attachments
Consider uploading documents to webpages and linking rather than attaching files directly.
Small tweaks add up, incrementally improving deliverability over the course of campaigns.
Ongoing Performance Benchmarking
The final step is establishing ongoing monitoring to benchmark your progress.
