What you get

A tool, not a bulk-mail service

Your mailbox, your rulesNo shared domains or someone else's servers: the message comes from you, and replies come back to you.

Write, don't codeHeadings, lists, links and the recipient's name, right in the app, with no HTML and no nested tables.

See what workedWho opened, who clicked and who opted out, per campaign, as it happens.

Everyone gets their own name

Type a name the way it appears in your sheet and watch what {{name}} turns into.

For developers

Send mail from your own code

One POST and the message leaves your Gmail. Campaigns over a sheet, templates with variables and statistics: all on the same key.

One message, one request, and the status comes straight back
Templates with variables: call them by id, pass values in the request
Campaigns over a Google Sheet: columns become variables
Events instead of webhooks: no server of your own to run

Try the API The key takes a minute to issue in the app. The API mailbox is separate, with its own daily cap.

POST /v1/messages

Authorization: Bearer ms_live_…
Content-Type: application/json

{
  "to": "client@example.com",
  "subject": "Order {{order}} confirmed",
  "template_id": "a7Kd93Xz",
  "variables": {"order": "A-1042"}
}

→ 201 {"id": "a3f…", "status": "sent"}

Common doubts

Is this a spam tool?

No. Messages go from your own mailbox at your own pace, unsubscribing is mandatory and immediate, and mailing purchased lists is forbidden by the terms.

How to stay out of spam

Who sees my addresses?

Nobody. The list is read from your sheet and used only for your messages: other users never see it and it never joins any shared database.

What does it cost?

There is a free plan and no card is needed: 300 messages a day. Pro lifts the daily caps, from 150 RUB a month. Gmail's own quota applies on both: about 500 messages a day on a free account.

Plans and what they include

How do I start a campaign?

Connect Google, paste a link to the sheet with addresses and names, write the message and start sending. The first campaign takes about five minutes.

Step-by-step guide

How is this different from Mailchimp?

Messages come from your own mailbox instead of a shared domain, the list stays in your own sheet, and you pay only to lift the daily caps, never for the size of the list. In exchange there are no ready-made designs, no sending domains of your own and no automated sequences.

Compared to Mailchimp and YAMM

Do I need to write code?

No. Everything is done with buttons in the app. There is an HTTP API, but it is for people who need to send messages from their own software.

What exactly the service does with Google data and who is responsible for what: the about page.

On deliverability: Gmail limits, staying out of spam, setting up SPF, DKIM and DMARC and getting off a blacklist. Check your own domain free and without signing up: SPF, DMARC, message headers.
