Acceptance Rate
Contrary to popular belief, not every email you send will land directly in your recipient’s inbox.
Often overlooked by email marketers, the Acceptance Rate is just as important as other key metrics that are gawked over. You know… like open rate and click rate.
In this short post, we'll define the Acceptance Rate and review its importance when compared to the other necessary metrics an email marketer needs to be on top of.
What is Acceptance Rate
The Acceptance Rate (also commonly referred to as the delivery rate) in email marketing refers to the percentage of sent emails that a recipient's email server accepts, regardless of whether those emails subsequently land in the primary inbox, spam folder, or another destination. It is a measure of successful email delivery at the server level.
How important is the Acceptance Rate?
Understanding the Acceptance Rate can actually make or break your email marketing strategy. While not as flashy as a high open rate, a high Acceptance Rate indicates that most of your emails are getting through to the mail server, which is the first step to reaching your recipient's inbox.
However, a low Acceptance Rate may point to various issues such as poor list quality, sending reputation, or email content that may be flagged by spam filters.
Keep in mind that even if your Acceptance Rate is 100%, it doesn't guarantee that your emails will land in the recipient's primary inbox. Other factors such as inbox management rules and recipient engagement will also continue to play a major role.
Why wouldn’t an email be accepted?
There are multiple reasons why an email may not be accepted by a recipient's mail server. Below are some of the common causes:
Server Misconfiguration: Technical issues or misconfigurations on the sending or receiving end can lead to non-delivery.
Temporary Server Issues: If the recipient's email server is down or facing technical issues, it might temporarily reject incoming emails.
Invalid Email Address: If the email address is incorrect, misspelled, or doesn't exist, the server will reject the email.
Full Mailbox: If the recipient's mailbox is full, it can't accept more messages until space is freed up.
Blacklisting: The sending IP or domain might be blacklisted due to previous spammy behavior or complaints. Email servers regularly check these blacklists to filter out potential spam sources.
SPF, DKIM, and DMARC Failures: These are email authentication methods designed to detect and prevent email spoofing. If these checks fail, it indicates that the email might not be from a legitimate source, leading the server to reject it.
Content Filtering: Some servers use content filters to scan emails for spammy or malicious content. If an email contains suspicious links, attachments, or phrases often found in spam, it might be rejected.
Attachment Issues: Large attachments or attachments with suspicious file types might cause an email to be rejected.
Poor Sending Reputation: If a sender frequently sends emails that are marked as spam, have low engagement rates, or go against email marketing best practices, the sending reputation can deteriorate to the point of emails being rejected.
It's worth noting that when an email is rejected, the sender typically receives a bounce-back message detailing the reason for the rejection. This message can often help in troubleshooting and resolving any underlying issue.
With these common causes in mind, there are some quick ways to help ensure that your emails are accepted. They’re pretty simple.
Authenticate your emails, keep a clean and engaged email list, and send genuine and wanted (not spammy) emails.
