# Sendfeather ## What it is Sendfeather is a transactional email service for product teams: send receipts, one-time codes, and notifications over SMTP or a single HTTP API call, and watch every message's journey from accepted to delivered. It also hosts real mailboxes for your domain, so sending and receiving live on one platform and one invoice. ## Pricing - Free: 1,000 emails a month, 1 hosted mailbox (1 GB storage each), no card required - Starter: $7 a month — 10,000 emails a month, then $0.70 per extra 1,000, 5 hosted mailboxes (2 GB storage each). - Pro: $15 a month — 50,000 emails a month, then $0.30 per extra 1,000, 25 hosted mailboxes (5 GB storage each). - Business: $29 a month — 100,000 emails a month, then $0.25 per extra 1,000, 100 hosted mailboxes (10 GB storage each). Yearly billing costs 10 months for 12 (Starter $70, Pro $150, Business $290 a year), and yearly plans meter at 10/12 of the monthly rate, so a full year of the advertised allowance bills exactly the yearly price. Emails past a paid plan's allowance are metered — sending never stops to ask for an upgrade. ## Why teams choose it - Cheaper than comparable SMTP2GO plans — $7 vs $15 at 10,000, $15 vs $30 at 50,000, $29 vs $75 at 100,000 emails a month. - A delivery timeline for every message — accepted, sent, delivered, opened, bounced — not just a log line. - Your mail is DKIM-signed with keys that are yours alone, so your domain's reputation is your own. - Mailboxes for your domain are hosted on the same platform, with webmail and IMAP, priced with the plan rather than separately. ## FAQ **What is Sendfeather?** A transactional email service: send receipts, one-time codes, and notifications over SMTP or an HTTP API, with a delivery timeline for every message — plus hosted mailboxes for your domain on the same platform. **How much does it cost?** Free workspaces send 1,000 emails a month. Paid plans: $7 for 10,000 emails, $15 for 50,000 emails, and $29 for 100,000 emails a month; yearly billing is ten months for twelve. Every paid plan includes hosted mailboxes for your domain. **Is there a free plan?** Yes — a free workspace sends 1,000 emails a month and includes 1 hosted mailbox (1 GB storage), with no credit card required. **What happens if I send more than my plan includes?** With monthly billing, extra emails are metered, not blocked: $0.70 per extra 1,000 on Starter, $0.30 per extra 1,000 on Pro, and $0.25 per extra 1,000 on Business. Nothing pauses to ask for an upgrade. **Does Sendfeather include mailboxes for my domain?** Yes — hosted mailboxes are part of every plan: 1 (1 GB) on Free, 5 (2 GB each) on Starter, 25 (5 GB each) on Pro, and 100 (10 GB each) on Business. They run on the same platform and the same invoice as sending. **Does it work with WordPress and Laravel?** Yes — Sendfeather is an SMTP relay as well as an HTTP API, so anything that can speak SMTP works: WordPress has the free Sendfeather SMTP plugin on WordPress.org (https://wordpress.org/plugins/sendfeather/), which sends over the API or SMTP, and a Laravel mailer only needs the host, port, and credentials from the dashboard. The docs walk through both setups step by step. **Can I use my own domain and DKIM keys?** Yes. Add your domain, publish the two DNS records the dashboard hands you (DKIM and DMARC) — or let the Cloudflare connection write them — and you keep sending from your own domain. Messages are DKIM-signed with keys that belong to your workspace alone. **Can I move over from my current provider?** Yes. The migration guide walks the cutover order, and the built-in importer can pull existing mailboxes across from your old provider over IMAP — your old provider keeps working the whole time. **Can I self-host Sendfeather?** No — Sendfeather is a hosted service; there is no self-hosted edition. The sending infrastructure, mailboxes, and delivery timeline all run on the platform for you. **How does Sendfeather compare with other providers?** Every provider we compare has a side-by-side page built from their own pricing page, with the date each price was checked: SMTP2GO, SendGrid, Brevo, Mailgun, Postmark, and Resend. At every comparable volume Sendfeather costs half of SMTP2GO or less. ## Docs - [Getting started](https://sendfeather.com/docs/getting-started): From sign-up to your first delivered email. - [SMTP](https://sendfeather.com/docs/smtp): Point any SMTP client at Sendfeather — no code required. - [SMTP relay](https://sendfeather.com/docs/smtp-relay): An SMTP relay takes your message and delivers it to the recipient's server for you.
