An AutoSend alternative with a free plan and a spend limit.
Samva is free for 3,000 emails a month, stops extra email at a spend limit you set, and keeps templates as versioned TSX in your Git repository. AutoSend has no free plan and states no cap on overage.
Who should switch, and who should stay.
- You want to start free. AutoSend has no free plan, and its Hobby plan is $1 for 3,000 transactional emails without webhooks. Samva is free for 3,000 emails a month.
- You want a hard limit on extra email. AutoSend charges a per-email fee past your quota and states no cap; it sends an email alert at 90% of quota. Samva stops extra email at the spend limit you set.
- You want templates as versioned TSX in Git, previewed and published from your repository.
- You need marketing automations. AutoSend's marketing plans include them; Samva has campaigns, not automations.
- You need an SMTP relay. AutoSend documents one; Samva has no SMTP relay.

Moving from AutoSend.
Add your domain and publish the DKIM and SPF records Samva generates next to the old provider's. Both can send while you switch.
Swap the send call.
AutoSend Node SDK or REST import { Autosend } from "autosendjs"; const autosend = new Autosend(process.env.AUTOSEND_API_KEY); await autosend.emails.send({ from: { email: "hello@yourdomain.com" }, to: { email: "ada@example.com" }, subject: "Your receipt", html: "<p>Thanks for your order.</p>", });Samva await samva.messages.send({ from: { email: "orders@example.com" }, to: [{ email: "ada@example.com" }], channel: "email", email: { subject: "Your receipt", html: "<p>Thanks for your order.</p>", }, });Map webhooks. Samva sends signed events for sent, delivered, bounced, complained, failed, and received. Opens and clicks are in the dashboard and the API, not webhooks.

Questions before you switch.
Does AutoSend have a free plan?
No. AutoSend's pricing page says it has no free plan and that its Hobby plan begins at $1, described as a small fee against abuse. Hobby is 3,000 transactional emails with no webhooks. Samva is free for 3,000 emails a month, 1,000 a day once a card is on file and 100 a day without one. Checked Sep 29, 2026.
What happens when I pass my AutoSend quota?
AutoSend charges a per-1,000 fee for additional emails and emails you when you reach 90% of your quota. Its pricing page states no cap on that fee. On Samva, extra email is $0.50 per 1,000 and stops at the spend limit you set. Checked Sep 29, 2026.
Does Samva have AutoSend's automations or SMTP?
No. Samva has campaigns, and no automations and no SMTP relay. AutoSend's docs list automations and an SMTP relay, so stay if your workflow depends on either. Checked Sep 29, 2026.
Is AutoSend billed on contacts?
No. AutoSend's pricing page says it charges for emails sent, not contacts saved, and Samva bills on emails as well, so this is not a reason to switch. Checked Sep 29, 2026.
