A peer warm-up network for real inboxes.

MailTantra's deliverability depends on warm-up mail routing through real, verified inboxes instead of a synthetic pool. List mailboxes you already own to join that network and earn credits (branded Rent & Earn), or spend credits to warm up your own sends.

How it works

Four steps. Then it runs itself.

01

List an inbox

Add an address you already own. We check its MX records, detect the provider, and verify ownership by email.

02

It gets rented

Members send warm-up mail to your address, capped by the daily limit you set. You earn a credit per use.

03

Earnings settle

Credits sit under a 48-hour hold, then release. No engagement means the sender is refunded instead.

04

Cash out

Withdraw to a bank account or UPI once you clear 500 credits. A flat 10% platform fee applies.

Two ways to use it

Earn from what you own, or rent what you need.

EARN

You already own the inboxes.

Every address you control is idle capacity. List it, set how much mail it should receive per day, and let it earn while you do nothing.

  • →Set your own daily receive cap
  • →Pause or remove a listing anytime
  • →Track every credit in one ledger
RENT

Reach real, verified inboxes.

Spend credits to route warm-up mail through inboxes owned by other members — real addresses on real providers, not a synthetic pool.

  • →Filter the marketplace by provider
  • →One credit per send
  • →Refunded if there’s no engagement

You control the daily receive cap and can pause or remove a listing at any time. Incoming warm-up mail is from real, verified members, not synthetic or spam-trap addresses.

Warm-up mail between real, consenting mailboxes is a standard deliverability practice, not the kind of bulk unsolicited sending providers police. That said, you’re responsible for complying with your own provider’s terms of service, and you can remove a listing immediately if you ever have concerns.
