A good fit is Action Network.
It’s commonly used for large advocacy broadcasts, and it offers:
- High deliverability
- Throttling/sending controls for very large sends
- Tools geared toward advocacy and mobilization
If you want, I can also give you a short comparison with similar tools like Mailchimp, Twilio SendGrid, or EveryAction.
