A successful check if email is active campaign relies on a strong list that’s free of typos, spam traps, and catch-all addresses. Unfortunately, many marketers build their lists organically and don’t always take steps to ensure that every address they add is valid. This can result in a high bounce rate and damage your deliverability.

If you have a small amount of time and want to check if an email is active, the simplest way to do so is to send it a test message. If the email doesn’t bounce back, then it’s most likely still active. However, this method can be extremely inefficient if you’re trying to verify hundreds of email addresses at once.

Another option is to use an email validation service that can scan the syntax, domain name, and ping the server to confirm if the email is active. While this may be a bit more expensive than simply sending a test email, it can help you weed out invalid emails that could be spam traps or temporary accounts and save your business from wasting resources on non-responsive contacts.

If you’re looking for a way to keep your email list clean and boost your deliverability rates, try implementing an email verification API into your signup forms. This will ensure that the emails that you’re emailing are real and have an active server, reducing hard bounces and protecting your sender reputation. Plus, you can even sift out those who are no longer interested in your content with a targeted re-engagement campaign.
