Frequently asked questions

How does the free plan work?

The free plan includes 3,000 emails per month (100 per day) permanently. Perfect for personal projects, staging or development. No credit card required.

Can I use my own domain?

Absolutely. In fact, we recommend it to improve deliverability. We provide the necessary DNS records (DKIM, SPF and Return Path) to verify your domain in minutes.

What happens if I exceed my monthly limit?

We'll notify you when you reach 80% and 100%. If you exceed the limit, you'll be charged a small fee for every 1,000 additional emails ($1.50) or you can upgrade your plan immediately.
