MailTantra vs Apollo

Apollo.io is primarily a sales intelligence and contact database platform with outreach sequencing built on top. Here's how it compares to MailTantra for agencies focused specifically on cold email.

Apollo's pricing is per-seat with credits that expire each billing cycle; its core differentiator is contact database size, not deliverability tooling. MailTantra is free during private beta with no credit card required and no per-seat pricing.

What Apollo users say
