Which Cold Email Tool Is Right for You?

If you send in bursts

A per-email tool like Alienmail costs less, because you pay nothing in months you don't send. A monthly plan bills you either way.

If you send a steady high volume every month

A flat plan can cost less per email. lemlist's $69 Email plan, for example, covers up to 50,000 emails.

If you need to find leads

Apollo and Snov.io include lead databases. Alienmail doesn't, so you bring your own list.

If you only need warmup

MailReach and Warmy.io are warmup-only. Alienmail includes warmup free, so you don't need a separate tool.

Why Teams Pick Alienmail

Three reasons teams move to Alienmail from a subscription tool:

01

No monthly fee

You pay per email, so a slow month costs $0.

02

The AI writes the campaign

Add your website and Alienmail writes the emails, follow-ups and send times.

03

Warmup, seats and workspaces are free

The things other tools charge extra for are included.

Comparison FAQ

It depends on how much you send. For senders who go in bursts, a per-email tool like Alienmail costs least because quiet months are free. For a steady high volume, a flat plan such as lemlist's can be cheaper per email. If you need a built-in lead database, Apollo or Snov.io fit.
