MailVeri

Email verification API to clean lists and cut bounces before you send.

Peplio's take

Bad email lists quietly kill email marketing. High bounce rates hurt your sender reputation, push your emails into spam and waste money on sending tools. MailVeri tackles this at a price that’s much easier on small businesses and bloggers than the big names in this space.

The biggest win is the pricing model. Most email verifiers sell monthly plans or credits that expire, while MailVeri’s credits never expire, so you only pay when you actually need to clean a list. The 1,000 free credits are enough to test it properly, and the integrations with Make, Zapier, Apollo and Clay make it easy to verify leads automatically.

The trade-off is that accuracy and speed numbers like 99% and under one second are the company’s own claims, so test it with your own list first. Catch-all domains also can’t be fully confirmed by any verifier. Best for email marketers, cold outreach teams, agencies and bloggers who build newsletters.
