The effectiveness of your email campaigns relies heavily on email deliverability—the ability to successfully land in recipients’ inboxes.
This article explores the key factors influencing email deliverability and provides insights into optimizing your email strategy for maximum reach and engagement.
Email deliverability is your email’s ‘green card’ to reach the intended recipient’s inbox without being filtered out or blocked by various email service providers (ESPs) and spam filters. You could say it’s a bit like the email’s immigration system — with your email hoping to be the one that gets through.
Then we have email deliverability rate — the statistic that quantifies your success (or failure) in getting past those email ‘border controls.’ This measure reflects the efficiency of your emails landing in the recipients’ inboxes and not being classified as spam or ending up in the junk folder.
A high deliverability rate is crucial for successful email campaigns, as it ensures that the intended audience receives and engages with your messages, leading to higher conversion rates and better business outcomes.
Email deliverability depends on several factors, including the reputation of the sender’s domain and IP address (aka your email infrastructure), email content, adherence to email authentication protocols (such as SPF, DKIM, and DMARC), engagement metrics (like open and click-through rates), and the overall quality of the email list.
Sometimes, you might come across another term instead of email deliverability – inbox placement. They’re two sides of the same coin, so you can use them interchangeably.
Unlike inbox placement, this one’s a bit different from email deliverability. Email delivery is more about whether the recipient accepts your email. For example, if your email fails to land anywhere in the first place, it’s fair to say that email delivery was unsuccessful.
Naturally, you’d aim for 100% email deliverability. But let’s be honest; the odds of reaching this top are slim. A good email deliverability rate is 95%, at least.
Given its complexity, email deliverability is hard to measure manually. That’s why there are various 3rd party solutions, like Glockapps, that come to the rescue.

Bad email deliverability means your emails don’t go right to the user’s inbox. Instead, they get bounced or end up in the spam folder. This is a sure sign you need to fix your email deliverability issues.
An email bounce, or bounce-back, is the boomerang of the email world. It’s when an email, instead of reaching the intended recipient, does a 180 and returns to the sender or an intermediary server with an error message. The sender typically receives a bounce-back message containing information about the reason for the failure.
There are two types of bounces: soft and hard.
An email returns as a soft bounce if:
If you suspect soft bounces are caused by email rejections and blocks, the reason might be that:
If you find yourself dealing with soft bounces, you need to first resolve the issue causing the bounce before trying to send your emails to the recipient again.
A hard bounce, on the other hand, indicates a permanent issue preventing your email from reaching its destination. It happens when:
To resolve the issue of hard bounces, you need to be sure all emails in your list are valid. That’s why you need to regularly verify your email list.
Keep in mind that sometimes email filters can mistakenly classify legitimate emails as spam and reject them, which results in bounces. This can happen if the sender’s email is flagged for suspicious content or the sender’s domain or IP address is blacklisted.
An email blacklist, also known as a blocklist or DNSBL (Domain Name System Blacklist), is a list of email servers or domains tagged as sources of spam or other forms of email mischief.
Email blacklists are used by ESPs, internet service providers, and other organizations that continuously monitor email traffic and collect data on servers or domains that exhibit spamming behavior or engage in other abusive practices. The goal of such monitoring is to protect their users from receiving unwanted or harmful emails.
Sometimes, being blacklisted can occur due to legitimate mistakes or misconfigurations. That’s why, as an email sender, your task is to keep a regular check on the email domain’s reputation. Think of it as checking your credit score, but for your emails. You can do this with the help of blacklist lookup tools such as MxToolbox or DNS Checker.
In case you’ve found your IP address or domain in any of the blacklists, you need to address the issue that led to the blacklisting. This could involve resolving security vulnerabilities, stopping any spamming activities, or improving email practices. Otherwise, your reputation and email deliverability are in danger.

Here are the basic tips on how to improve email deliverability:
Regularly clean and update your email list by removing inactive or invalid email addresses. Use confirmed opt-in or double opt-in methods to ensure recipients have explicitly requested to receive emails from you.
Unsubscribing should be as easy as subscribing. So honor unsubscribe requests promptly, provide clear instructions on how to opt-out, and remove the unsubscribed email addresses from your list.
Use reputable ESPs that have good deliverability rates. Authenticate your emails with SPF, DKIM, and DMARC records. And remember to warm up your email account before sending out bulk email campaigns.
If your IP address is shared with others (i.e., used by multiple senders), there’s always a possibility they might be sending unsolicited emails from the same IP address. So if you’re a high-volume sender, consider using a dedicated IP address, one that is only used by a single sender.
Make sure your email content doesn’t raise any spammy red flags. Use meaningful subject lines, steer clear of excessive capital letters or exclamation marks, and refrain from using spam-related keywords.
Keep a close eye on your open rates, click-through rates, and spam complaint rates. If you’re seeing high engagement and low complaints, you’re hitting the right notes!
Keep tabs on your bounce rates. It’s okay to retry soft bounces (temporary delivery failures), but hard bounces (permanent delivery failures) warrant immediate removal from your email list.
Actively investigate and address any abuse reports or complaints received from recipients or ESPs. Promptly take appropriate actions to rectify any issues causing the complaints.
