Most ESPs (including EmailOctopus) automatically remove hard bounces from your mailing list. The more you email contacts that return a hard bounce, the more likely you are to fall foul of spam filters. Internet Service Providers (ISPs) set limits for bounces, as well as spam complaints and unsubscribe requests. And hard bounces damage your sender reputation, which hurts your deliverability. Invalid and non-existing email addresses will return a hard bounce.

Which will improve your ability to build more meaningful relationships with your audience. You’ll then be able to make better informed decisions when engagement peaks or dips. But your metrics will give you a more accurate picture of what’s working with your target audience. Granted, the number of people opening or clicking your emails won’t change. If you remove contacts that are not opening your emails, the percentage of subscribers who do open your emails will go up. Open rate is calculated as a percentage – the number of opens divided by the number of emails sent. When you’re sending your emails to people who want to hear from you, your open and click rates will naturally increase. And you’ll rewarded with better campaign performance, better deliverability and cost savings. By regularly purging your mailing list of these invalid and inactive subscribers, you’ll craft a more engaged audience. Neither of these types of contacts make for a healthy mailing list. These are the contacts that signed up to your mailing list but haven’t opened a single email from you. Then there’s the issue of inactive, or ‘cold’, subscribers. Or they simply don’t check that particular account anymore. It could be because a contact signed up with a work email but then changed jobs. Not all email addresses on your list remain valid.
