Two real send volumes worked out in full, and a six-provider breakdown for everything between and beyond them: what sending email actually costs, with the arithmetic shown rather than a single number.
sendvia's own figure at this volume is $29.00: a flat $19.00 plus Amazon SES billed at cost. The full guide shows what the other five providers charge for the same volume, with the working behind every figure.
At ten times the volume, sendvia's figure is $119.00, because only the Amazon SES half of the bill moves with volume. The full guide works through that arithmetic and what it takes to actually reach that volume, sandbox limits and API caps included.
The full breakdown prices sendvia, Resend, Postmark, Mailgun, SendGrid and raw Amazon SES at seven volumes from 1,000 to 5,000,000 emails a month, and is honest about where a free tier beats sendvia outright rather than only showing the volumes where sendvia wins.
| Emails per month | sendvia | Resend | Postmark | Mailgun | SendGrid | Raw SES |
|---|---|---|---|---|---|---|
| 10,000 | $20.00$19.00 + $1.00 SES | $20.00 | $15.00 | $15.00 | Not publishedSendGrid does not print a price against a send volume. See their pricing page. | $1.00 |
| 100,000 | $29.00$19.00 + $10.00 SES | $35.00 | $126.00Based on Postmark's Platform plan at $18.00 plus their published $1.20 per additional 1,000. | $90.00 | Not publishedSendGrid does not print a price against a send volume. See their pricing page. | $10.00 |
| 1,000,000 | $119.00$19.00 + $100.00 SES | $650.00 | $1,206.00Based on Postmark's Platform plan at $18.00 plus their published $1.20 per additional 1,000. | $1,080.00At least $1,080.00. Computed from Mailgun's published $1.10 per additional 1,000 above 100,000 emails, staying on their $90.00 tier. That rate is published as a "from" price, so treat this as a lower bound. | Not publishedSendGrid does not print a price against a send volume. See their pricing page. | $100.00 |
| Prices verified . Each figure is the cheapest route worked out from what a provider actually publishes. Some are a quoted plan price; others are computed from a published rate for extra emails, and a note beside those says so. sendvia cost is a flat $19 plus Amazon SES at cost. | ||||||
Every figure on all three guides comes from the same pricing data as the cost calculator and the per-provider comparison pages, so a number checked on one page will match the same number wherever else it appears.
