New entrepreneurs often learn the hard way that reaching the inbox isn’t as simple as it sounds. If you don’t verify the email addresses on your list, you’re inviting high bounce rates and IP/domain blacklists to ruin your campaign. Those are big problems to fix ASAP. Poor email hygiene will dent campaign performance, reputation, and revenue.
The good news is that there’s no shortage of email deliverability tools to help you reach a solid deliverability rate. And email verification is the starting point.
An email verifier is a quick way to check if an email address is real, active, and safe to message. It’s a regular habit for bulk senders, as too many bounced emails hurt your sender reputation, which will eventually send your emails to spam. So, regularly cleaning your email list will save you a lot of trouble.
Here are 5 free email verification tools to get you started.
