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) |
| Certifications | Twilio trust center: SOC 2 Type II, ISO 27001 | None yet — stated plainly on an open security page |
| 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: 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.

Questions, answered plainly
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.
