Email Performance Insights: High Hard Bounce Rate
This email had a high hard bounce rate when compared to the emails sent in the last 30 days.
A hard bounce is a permanent bounce, meaning an email will not be received by that email address. It may be the result of an unknown user error, which is caused when an email address:
- Is invalid because it doesn’t exist or contains a typo (e.g., @gmial.com instead of @gmail.com).
- Has been deactivated, such as when someone leaves a company or abandons a free email account.
- Has blocked your emails from being delivered.
Our recommendations for managing bounce rates:
- Actively managing hard bounces is critical. Determine your specific ESP’s practices to ensure a process is in place for all key elements. Do they automatically correct common email address typos? After how many hard bounces will your ESP mark an email address undeliverable? And for which kinds of hard bounce?
- Set rules for deactivating hard bounces and add them to a suppression list as part of your list hygiene practices. Doing this removes the possibility that you’ll accidentally send to email addresses you know will hard bounce.
- Also consider creating suppression lists of commonly misspelled email domain names to avoid sending to them in the first place.
- Actively manage the data quality of your list to reduce bounce rates. Repeatedly sending email to addresses that hard bounce can indicate to internet service providers (ISPs) that you have bad list hygiene practices. Data quality is an important metric for ISPs when they’re deciding whether your emails are spam or not and can contribute to your sender reputation.
- Actively managing your list isn’t just good for deliverability, it’s good for engagement, too. (Which is, in turn, good for deliverability.) When you send to a cleaner list, you’re more likely to be sending to people who want to receive and will engage with your email. That’s a win-win.
