Zapmail sells Google Workspace and Microsoft 365 mailboxes in bundles: $39 a month for ten, then $3.50 each, with automated DNS and a five-minute setup. The two things buyers discover later are in the help center rather than on the pricing page: after twelve months each mailbox steps up to $5 to $6 plus a base fee of $59 to $499, and payments are not refundable.
Why people look for a Zapmail alternative

How to choose
- Decide who owns the domains and accounts. Some vendors keep ownership or administrator access; if you may leave, you want yours in your own name.
- Count the year-two price, not the launch price. Several infrastructure vendors step prices up after twelve months or sell pre-warmed mailboxes that expire.
- Ask what happens when a domain burns. Replacement policy, and whether the vendor pauses the sender or quietly suppresses your recipients.
- Check the review sites for cancellation stories. They are the most consistent complaint in this category across vendors.
- Send at 8 to 10 a day per mailbox whatever you buy. No vendor's mailbox survives 100 a day to strangers.
Questions, answered straight
- Which Zapmail alternative lets me keep the domains and accounts?
- Premium Inboxes has you bring your own domains. emailcampaign.ai registers domains in your name and creates the Workspace or Microsoft accounts under your ownership, with credentials in a vault you control. Instantly's pre-warmed accounts stay under Instantly's ownership and administrator access.
- What does a Google Workspace mailbox actually cost?
- Google's flexible-plan list price is $8.40 a user a month. Resellers quoting $2.50 to $4.50 are pooling discounted seats under their own accounts; that is legitimate, but it is also why ownership and year-two pricing are worth reading. emailcampaign.ai bills the $8.40 seat at cost plus a one-time $5 setup, and the account is yours.
- Do I still need warm-up if the mailboxes come pre-warmed?
- Yes. Pre-warming gives a mailbox a history; it does not keep one. Warm-up should continue at a maintenance level for as long as the mailbox sends cold email.
