I got tired of paying $20/month for emails I didn't send.

Hey — I'm the person behind SendexAPI. 👋 I'm an indie developer and I run a lot of projects at once. Each one needs transactional email — password resets, welcome emails, notifications.

Every provider I tried wanted a monthly subscription. $20 here, $15 there. Most months my projects barely sent anything, but I was paying full price regardless. It felt like renting a truck every month just in case I needed to move a box.

I just wanted to pay for what I actually sent. That's it. But no one offered a simple, clean pay-per-use email API without a catch.

So I built one. SendexAPI — $1 per 1,000 emails, no monthly fee, no nonsense. Buy credits when you need them. Pay nothing when you don't.

It's the email service I always wanted. Hope it works for you too.

Common answers below — or just send us a message.

We usually reply within a few hours.

How does the credit system work?

You buy credits upfront — $1 gets you 1,000 email sends. Each email deducts one credit. No subscription, no monthly charge, no minimum spend. Top up when you need to.

Do credits expire?

Never. Buy a batch today and use them a year from now. Your quiet months cost $0.

Can I receive emails too, not just send them?

Yes. Once your domain is verified you get a full inbox in the dashboard. Read, reply, download attachments, and organise by folder — all from the webmail interface.

Can I send to mailing lists and newsletters?

Yes. Create an audience, import contacts via CSV, set up subscription topics, and send broadcast emails from the dashboard or API. Unsubscribe pages are generated automatically.

How does the AI template builder work?

Open the template editor, describe the email you want in plain English, and the AI generates the HTML. You can then edit it directly, tweak the design with brand colors and fonts, and preview it live before sending.

How long does domain verification take?

DNS changes usually propagate within a few minutes, though it can take up to 24 hours depending on your provider. The dashboard shows the status of each record in real time.
