AlienMail vs Mailshake FAQ
Everything you need to know about comparing AlienMail with Mailshake.
Why do teams look for a Mailshake alternative?
Per-user pricing is the usual trigger. Mailshake's Email Outreach tier runs $59 per user per month, so a three-person team pays roughly $177 before sending. Teams also want native inbox warm-up, which Mailshake does not provide, and monthly recipient caps become limiting as volume grows.
How does AlienMail pricing compare to Mailshake?
AlienMail charges $0 monthly and $0 per seat, billing only on emails sent — $5 for 5,000, $15 for 25,000, $50 for 100,000. Mailshake starts at $29 per user per month for email-only Starter, with most outbound teams landing on the $59 or $99 per-user tiers.
Does Mailshake include inbox warm-up?
Mailshake does not offer native peer warm-up, so teams typically pair it with a separate warm-up service. AlienMail includes automated warm-up free across unlimited connected mailboxes.
Does AlienMail have a phone dialer like Mailshake?
No. Mailshake's higher tiers bundle a dialer and LinkedIn automation. AlienMail is a dedicated cold email and deliverability engine, which is why the cost structure is per-email rather than per-seat.
Can agencies run multiple clients on AlienMail?
Yes. Workspaces and seats are unlimited at $0, so each client can have an isolated workspace without an agency upgrade — something Mailshake does not natively support.
