Where they pull apart

Aerosend

Stands out: Warmup, biweekly inbox placement tests, and burn replacement sit in the $4 inbox price.

Watch out: A 21-day warmup runs before you send. The one-month-free code is a promo, not a trial. Minimum displayed pack is 30 inboxes.

Not the right fit for

Buyers who need to send the same day they pay
Teams that want a free trial rather than a promo code

Zapmail

Stands out: Pre-warmed US/EU Google and Microsoft mailboxes with automated DNS and OAuth export to sequencers.

Watch out: API access starts on Pro at $299/mo. Extra Google mailboxes cost $3.50 each on Starter.

Not the right fit for

Buyers who need API access on Starter
Teams that want dedicated SMTP IPs they control
