# Looking for a SendGrid alternative?

> SendGrid is mid-migration into Twilio and its free tier is now a 60-day trial. Email Fast accepts your SendGrid SDK unchanged — an honest comparison.

Canonical: https://emailfast.dev/compare/sendgrid-alternative

SendGrid is mid-migration into Twilio: sendgrid.com now redirects to a Twilio
interstitial, and the perpetual free tier is gone, replaced by a 60-day trial at 100
emails a day. If that prompted your search, the short version is that
SendGrid-, Mailgun-, and Postmark-compatible endpoints: point your existing SDK at a new base URL with a new key and keep your code. The honest counterweight: Twilio maintains a substantial trust
center with certifications we don't hold, and if you want email, SMS, and voice under
one vendor, Twilio is that vendor and we are not.

## The comparison

| | SendGrid (Twilio) | Email Fast |
|---|---|---|
| Brand | Mid-migration into Twilio; email is one product inside a telecom platform | Independent; email is the entire company |
| Free tier | Discontinued — now a 60-day trial at 100 emails/day | 2,500 emails/month, never expires; free sends carry a “Sent with Email Fast” footer that paid plans remove |
| Paid entry | From about $19.95/month | Starter, $9.90/month for 20,000 emails ([pricing](/pricing)) |
| Certifications | Twilio trust center: SOC 2 Type II, ISO 27001 | None yet — stated plainly on an open [security page](/security) |
| Drop-in migration | — | SendGrid-, Mailgun-, and Postmark-compatible endpoints: point your existing SDK at a new base URL with a new key and keep your code |

## Keys and proof

No mainstream platform hands you the keys — as of July 2026, none of the twelve competitor platforms we surveyed offers customer-held encryption keys for message content — the closest, a healthcare email provider, documents that its master keys live in its own cloud KMS. Email Fast is
built for the other answer: organizations can bring their own encryption keys — enroll, rotate, suspend, or revoke — and revocation fails closed: new sends are rejected and stored secrets become unreadable, to us included. And when a send matters enough to prove,
delivered messages can mint an Ed25519-signed delivery certificate — receiving mail server, TLS details, the server's SMTP response, and timestamps, with the recipient stored only as a keyed hash — chained into a tamper-evident ledger and verifiable without trusting us.

## Where SendGrid is the right choice

- **You're already a Twilio shop.** Email, SMS, and voice under one account and one bill beats stitching vendors together.
- **Procurement needs third-party attestation today.** Twilio's SOC 2 Type II and ISO 27001 are real and current; our audit roadmap is not a certificate.
- **You want a large, established vendor.** Email Fast is in early access. If that risk profile is wrong for you now, it's wrong — and the 60-day trial gives you time to evaluate Twilio properly.

## Switching

Point your existing SendGrid SDK at our base URL with an Email Fast key — the
compatible endpoint accepts `/v3/mail/send` requests unchanged. Today that means a
[sandbox key](/get-started): sandbox keys (ef_sandbox_…) that run the real pipeline dry: real validation, real rendering, real events, a hosted capture inbox — and no email leaves. Live delivery opens at launch. The
step-by-step path, including domain verification: [/migrate/sendgrid](/migrate/sendgrid).

## Is SendGrid shutting down?

We don't know, and we won't speculate. What we verified on July 17, 2026: sendgrid.com redirects to a Twilio interstitial, the brand is mid-migration into Twilio, and the perpetual free tier has been replaced by a 60-day trial at 100 emails a day. That's what their pages say; the rest is guesswork.

## Do I have to rewrite my code to switch?

No: SendGrid-, Mailgun-, and Postmark-compatible endpoints: point your existing SDK at a new base URL with a new key and keep your code. For SendGrid that means your existing SDK keeps posting to /v3/mail/send — you change the base URL and the key. The full path: /migrate/sendgrid .

## Does Email Fast have SendGrid's certifications?

No. Twilio's trust center holds SOC 2 Type II and ISO 27001 — credit where due. We hold no third-party attestations yet and say exactly that on the security page , alongside what we ran instead — a 19-stage adversarial security review, run to zero confirmed findings. That review was internal and adversarial — a documented find→refute→fix→re-verify loop — not a third-party audit. We say exactly which one we have.

## What replaces the free tier SendGrid removed?

Ours: 2,500 emails a month with full platform features and an unlimited test sandbox. It never expires and never asks for a card. Free sends carry a small “Sent with Email Fast” footer; every paid plan removes it.
