Instantly sells done-for-you Google accounts at $5 a month, pre-warmed ones at $10 and AirMail SMTP inboxes at $4, on top of a sending plan. Instantly keeps the domains, and the accounts work only inside Instantly. These alternatives sell mailboxes you can take elsewhere. Outreach2day is first: $2.50 with warmup and a sequencer, or $2.50 synced into your Instantly account. We make it.

Why Outreach2day tops this list

  • The domains are yours

    Instantly's help center says it retains domain ownership and admin access of done-for-you purchases and can't transfer them. Domains bought in our app are registered with your details.

  • Half the price per mailbox

    $2.50 against $5 for a done-for-you Google account. Keep the Instantly plan if you like it: at 100 mailboxes the mailbox line drops from $500 to $250 a month.

  • Mailboxes that leave with you

    Ours sync to Instantly and Smartlead by API key and export as CSV to 14 tools. Instantly's done-for-you accounts can't be used anywhere else.

Instantly sells Google accounts, a lead database and a CRM in the same tool. Ours are SMTP/IMAP mailboxes that sync into it.

How we count: 550 cold emails per mailbox a month (25 a day on 22 working days), the same for every vendor. List prices on monthly billing, in USD, excluding domains, taxes and discounts. A vendor that does not sell sending gets the cheapest Instantly plan that covers the volume.

The details

Replace the accounts or replace Instantly as well

List the campaigns that depend on done-for-you, pre-warmed or AirMail accounts before buying a replacement. Keeping Instantly means its sending-plan bill stays, even if the account supplier changes. Compare the mailbox invoice on that basis and check that the replacement can connect to your existing workspace.

Leaving the sequencer as well requires a second handover: campaign steps, remaining contacts, replies and opt-outs must reach the new sender. Preserve the do-not-contact list so a cancelled address does not cause an old contact to enter a fresh sequence. Use new sending domains because the done-for-you domains cannot transfer, and let the replacement accounts finish their own warmup. Cancel the old accounts after live conversations and scheduled campaigns have an owner in the new setup.

What Instantly's accounts cost, and what replaces them

See Instantly pricing 2026 for its plans and account types, or Outreach2day vs Instantly for the full product comparison.

Instantly's accounts: $5 a month for a done-for-you Google account, $10 pre-warmed, $4 AirMail, with domains at $15 a year and at most 5 accounts per domain. The Outreach plan is separate: Hypergrowth at $97 covers 100 mailboxes sending 25 a day.

Keeping Hypergrowth and replacing only the accounts at 100 mailboxes: $500 of done-for-you accounts becomes $250 with ours, $299 with Zapmail Pro or $300 with InboxKit. Pre-warmed accounts at $10 would be $1,000.

Full setup with Instantly's own accounts: $222 at 25 mailboxes, $597 at 100, $2,184 at 400. With ours and our sequencer: $62.50, $250, $1,000.

Pre-warmed accounts against warming your own

Instantly's pre-warmed accounts send within minutes of purchase but start at 5 emails a day per account and are capped at 20–25. They cost $5 a month more than a done-for-you account for as long as you keep them.

Our mailboxes are ready within 24 hours and warm up for 14 days before the first cold email; they reach up to 25 a day around day 21. If you can wait three weeks, the difference at 100 mailboxes is $1,000 against $250 a month.

Who owns what when you cancel

Instantly's done-for-you and pre-warmed accounts: Instantly keeps the domains and admin access. Cancelling pre-warmed accounts takes effect immediately, and access to the Gmail mailbox ends shortly after. Replies still in those mailboxes go with them.

Outreach2day: domains bought in the app are registered for a year with your details, and support moves them to your own Namecheap account on request. Cancelled mailboxes are deleted and can't be restored, so move campaigns first. There is no charge after the paid month.

Zapmail and InboxKit: their pages say domains bought through them are yours. Maildoso keeps domains registered with itself while it services them and transfers them out for free on request.

Moving off Instantly's done-for-you accounts

  1. Create mailboxes in Outreach2day on new domains. The done-for-you domains stay with Instantly, so start with fresh ones.
  2. Warmup starts on its own. Send no cold email from the new mailboxes for the first 14 days.
  3. Connect Instantly with an API key; the mailboxes appear in your Instantly workspace.
  4. Move campaigns to the new mailboxes as they ramp to 25 a day around day 21.
  5. Cancel the done-for-you accounts last. Cancelling pre-warmed accounts takes effect at once and access to the mailbox ends soon after, so move replies first.

Instantly alternatives: questions

Can I use my own mailboxes in Instantly instead of done-for-you accounts?

Yes. Every Instantly Outreach plan allows unlimited email accounts. Outreach2day mailboxes are added to your Instantly workspace by API key.

Can I take Instantly's done-for-you domains with me?

No. Instantly's help center says it retains domain ownership and admin access and can't transfer them, and the accounts work only inside Instantly. Start on new domains.

What is the cheapest alternative to Instantly's done-for-you accounts?

Outreach2day at $2.50 per mailbox, against $5. At 100 mailboxes with our sequencer, $250 a month; with Instantly Hypergrowth kept as the sender, $347.

Are there alternatives that sell Google accounts like Instantly?

Zapmail, InboxKit and Premium Inboxes sell Google Workspace and Microsoft 365 mailboxes, and the domains are yours. Outreach2day sells SMTP/IMAP mailboxes.

Is this the same as Outreach2day vs Instantly?

No. This page is about replacing Instantly's accounts. The side-by-side of the two products, sending included, is at Outreach2day vs Instantly.
