FAQs

1. Is email verification still a big deal in 2025?

It’s actually more of a "must-have" now. Spam filters have gotten so aggressive that even a few bounces can get your entire domain flagged. You are essentially requesting to be blocked if you continue to send emails to phony or outdated addresses. Having a neat list is not as important as ensuring that the emails you truly care about are received by actual people.

2. Is bulk verification adequate, or does real-time address verification really matter?

Ideally, both! Bulk verification is like a "deep clean" for your existing lists. You’d use this before a big campaign or when importing an old database into your CRM. Real-time verification is like a security guard at the door. It catches typos and fake emails right at the sign-up form. So, the "junk" never gets into your system in the first place.

3. How often should I be cleaning my lists?

You must run a check before every big email blast. No one likes a bunch of bounces out of nowhere. Do it on a set schedule too, since people switch jobs and email addresses all the time. And when user sign up, use real-time tools to catch bad emails right away. That way, you’re always working with good data.
