People change their emails all the time or they forget their passwords so they just make new email addresses. This is why it's very important to clean your mailing list before every email campaign. You can use an email validation service like MailboxValidator.com to remove old and stale emails.
That will normally keep your bounce rate to an acceptable level.
However, you should also check if your email contents are spam-like. If you're using an Email Service Provider like MailChimp, you should have access to tools that can screen your content for spam-like texts. Modify your content as needed. If your content is deemed to be spam, some ISPs will just bounce your emails.
Do the above and you should see your bounce rate dropping to a manageable level.
There are several strategies you can use to try to reduce the bounce rate in your email marketing campaigns:
- Ensure that your email list is up-to-date and accurate. Make sure you are sending emails to valid, active email addresses.
- Use double opt-in to confirm that the email address belongs to the person you are trying to reach. This can help reduce the number of bounced emails due to typos or incorrect addresses. If you prefer a no-friction process - use real-time email verification to prevent typos.
- Use an email verification service to check the validity of your email addresses before sending your campaigns.
- Use a reputable email service provider (ESP) that has a good reputation for delivering emails to the inbox.
- Test inboxing (perform seed tests) using a Deliverability Kit.
- Monitor and analyze your bounce rates regularly to identify any patterns or issues that may be causing a high bounce rate.
By following these strategies, you can help reduce the bounce rate in your email marketing campaigns and improve the chances that your emails will be delivered to the inbox.
First, you will need to see what is triggering the bounces and after that, you can make a strategy on what to do to lower it.
In case you have bounces because you have emails on your Email List that are no longer in use I recommend using an Email Validation Service so that you can send your Email Campaign only to existing emails. This way your bounce rate will be very low.
Another thing to do is to make sure that you have your Template as clean from words that might identify the email as spam by spam engines. So any words that depicts emergency or are reapeted might trigger the spam engine.
And the last thing that you need to do is to warm-up your IP, this procedure will help you to prevent bounces and your Email Campaign to reach as many Inboxes as possible. The warm-up is meant to improve the Email Sending Reputation. Most servers don't let your email enter their Inbox if they see you have a low reputation. There are different warm-up strategist and the one that I recommend is to focus on emails that open your emails frequently. First you will gather these emails addresses, then you need to verify them via Email Verification to take only the valids, after that you need to send your campaign to a few of these emails and week by week to increase the number of recipients. This might help you also.
I hope my recommandations will help you!
