Questions & Answers

As answered by people managing Mailfully and SendGrid Email API.

What makes your product unique?

Mailfully's answer

Mailfully is an email API with simple, published pricing. There's a free plan with 5,000 emails a month, and paid plans start at $19 for 50,000. Every paid plan has the same overage rate, $0.40 per 1,000 emails. You can also receive email through the same API, and every message has a log so you can see what happened to it.

Why should a person choose your product over its competitors?

Mailfully's answer

It costs less. At 500,000 emails a month Mailfully is $149, compared with $350 at Resend. At 50,000 emails it's $19 compared with $55 at Postmark. The free plan is 5,000 emails a month, and every plan keeps 30 days of message logs. You also get a dedicated IP on the Scale plan without paying for a separate upgrade.

How would you describe the primary audience of your product?

Mailfully's answer

Developers and small teams who send email from their own apps: sign-in links, receipts, password resets and notifications. It's a good fit for startups that want a real free plan, and for teams leaving Resend, Postmark or SendGrid that want a lower bill.

What's the story behind your product?

Mailfully's answer

We wanted a simple way to send email from an app without guessing what the bill would be. Amazon SES is cheap but hard to set up and debug, and most APIs built on top of it or competing with it charge a lot more. So we built Mailfully: SES underneath, with a clean API, a dashboard and prices you can read on one page.

Which are the primary technologies used for building your product?

Mailfully's answer

The API is TypeScript on Node.js using Hono, with PostgreSQL and Redis. It runs on AWS (SQS, SNS, Fargate). The dashboard and website use Next.js, and billing is through Stripe.
