Anything

Add email sending with MailBlastr to an Anything project by adding the API key as a project secret.

Anything is a platform for building sites, tools, apps, and projects via chat. You can send email from your Anything project by asking the chat to add email functionality with MailBlastr.

1. Ask Anything to add email

In the chat, ask Anything to add email functionality to your project and have it call the MailBlastr API. In Node.js projects, the generated function can use the official mailblastr SDK (npm install mailblastr) and call mb.emails.send(...). In other runtimes it sends with a plain HTTP POST to https://api.mailblastr.com/emails.

2. Add your MailBlastr API key

Anything usually prompts you for an API key. If it doesn't, open the project's More options menu and select Secrets, then add a new secret:

Namestringrequired

Use MAILBLASTR_API_KEY.

Valuestringrequired

Your MailBlastr API key (e.g. mb_xxxxxxxxx), created in the dashboard.

Do not share your API key or expose it in client-side code. Store it as a project secret.

3. 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 update the from field in the function to use an address on that domain.
