# Which mailer should I use?

import { CheckYourself, MailerChooser } from '@booleanpress/learn';
import { cards, questions } from '../../../data/learn/chooser';

BooleanSMTP sends through five mailers. Most sites fit one of three situations:

- **Your business email is on Google Workspace or Microsoft 365.** Send through that account: you connect by signing in.
- **Your site sends a lot** — shop orders, memberships, newsletters. Use Amazon SES, a sending service built for volume.
- **Your host or mailbox gives you SMTP details.** Use **Custom SMTP**.

**PHP Mail** is WordPress's default sending, with no provider behind it — a last resort rather than a choice.

## Find your fit

Pick an answer to each question; the list re-orders as you go, and the top three say why.

Each card opens that mailer's setup guide. The full list is on [Mailers](/docs/mailers/).
