Letterhead vs SendGrid

# SendGrid sends email. Letterhead runs your newsletter business.

SendGrid (Twilio) is a developer email API — great for transactional and bulk sending, but it was never a newsletter platform. No editorial workflow, no monetization, no portfolio. That's the part publishers actually need.

- Purpose-built for newsletters — not a raw email API
- Editorial production, monetization, and intelligence in one place
- Publisher-grade deliverability without building the infrastructure yourself
- Easy to move — send with Letterhead, or keep SendGrid for transactional if you need to

Trusted by New York Post, Condé Nast, Townsquare Media, and hundreds more.

_API vs. newsletter platform_

## An email API isn't a newsletter program.

### SendGrid delivers messages

It's built for developers sending transactional and bulk email. There's no editorial workflow, no portfolio, and no way to monetize a send.

### Letterhead runs the whole program

Drag-and-drop production with approvals, a portfolio view across every title, audience intelligence, and direct + programmatic + house ads built in.

### Deliverability, handled for you

Publisher-scale sending with dedicated IP pools and deliverability management — without standing up and maintaining the infrastructure yourself.

“We've never seen open rates this high before in the history of our sending.”

— Townsquare Media

## Questions, answered.
Can we keep SendGrid for transactional email?
Yes. Many teams keep SendGrid for transactional/app email and run their newsletter program on Letterhead — editorial, monetization, and intelligence in one purpose-built place.
What about deliverability?
Letterhead is built for publisher-scale sending — dedicated IP pools, deliverability management, and best-in-class inbox rates — managed for you, not assembled from API parts.
Do we have to migrate everything?
No heavy migration. Moving is fast — live in days — and we map your templates and audiences for you.
Is Letterhead built for large publishers?
Yes — New York Post, Condé Nast, and Townsquare Media run newsletter portfolios on Letterhead.
