AlienMail vs Reply.io FAQ
Everything you need to know about comparing AlienMail with Reply.io.
Why do teams look for a Reply.io alternative?
The most common reason is per-seat pricing. Reply.io starts at $59 per user per month, so a five-person outbound team pays roughly $295 a month before sending anything. Teams also cite active-contact credit caps and the cost of keeping licences active during slow quarters.
How does AlienMail pricing compare to Reply.io?
AlienMail has no monthly retainer and no seat fees. You pay only for emails sent — $5 for 5,000, $15 for 25,000, and $50 for 100,000. Reply.io charges from $59 per user per month regardless of send volume, and that licence continues to bill in months when campaigns are paused.
Does AlienMail support LinkedIn and calling like Reply.io?
No. Reply.io is a multichannel engagement suite that bundles LinkedIn touches, calls, and SMS. AlienMail is a dedicated cold email and deliverability engine. If multichannel sequencing is core to your motion, Reply.io covers it; if email is where your pipeline comes from, AlienMail delivers the same volume at a fraction of the cost.
Can I add unlimited team members to AlienMail?
Yes. Team seats and workspaces are unlimited at $0 on AlienMail, which is the main structural difference from Reply.io's per-user licensing. Agencies can run a separate workspace per client without an agency upgrade.
Is inbox warm-up included with AlienMail?
Yes. Automated peer warm-up is free across unlimited connected mailboxes, with no per-inbox charge and no tier cap.
