Replit

Replit is a platform for building sites and apps with AI. You can add MailBlastr to a Replit project by asking the chat to add email sending with MailBlastr.

Example prompt

When someone fills out the contact form, send an email using MailBlastr.

1. Add a custom domain

By default you can only send email to your own address. To send to other recipients, add and verify a custom domain, then use an address on that domain as the from address in the next step.

2. Add your MailBlastr API key and from address

Create a MailBlastr API key in the dashboard and store it as a secret (e.g. MAILBLASTR_API_KEY). The from address is the verified address your email is sent from — use the custom domain you added in step 1 (e.g. hello@example.com). In Node.js Repls, Replit can install the official mailblastr SDK (npm install mailblastr) and call mb.emails.send(...). In other languages, the generated code calls the MailBlastr API over plain HTTP.
