Zapmail vs Instantly: what's the difference?
Zapmail sells mailboxes you connect to any sequencer. Instantly is a sending platform that also sells done-for-you mailboxes; per Instantly's help center, those accounts are paused without a paid Instantly plan.
Can I connect Zapmail to Instantly?
Yes. Zapmail lists Instantly among its 50+ integrations, so Zapmail mailboxes can be connected to Instantly campaigns. Jetmail mailboxes connect to Instantly with 1-click OAuth too.
Which is cheaper?
For 30 standard mailboxes billed monthly: $99 on Zapmail vs $150 on Instantly, before Instantly's required sending plan (from $47/mo). Instantly's pre-warmed accounts are $10/mailbox, Google only.
Who owns the domains?
Instantly's help center says it keeps ownership of domains bought for its done-for-you accounts and won't transfer them. With Zapmail and Jetmail, domains you bring stay yours, and Jetmail registers domains bought in its dashboard to you.
Is there a third option?
Jetmail works with Instantly like Zapmail does, at the same plan prices, with pre-warmed Google and Microsoft inboxes from $6.00 per mailbox.
