Overview
Broadcasts let you send marketing emails — newsletters, announcements, product updates, and campaigns — to your contact audiences. Unlike transactional emails, broadcasts are unlimited on all plans. Your plan’s contact limit determines your audience size, not how many broadcasts you can send.Broadcasts are unlimited. Your plan determines how many contacts you can have — you can send unlimited broadcasts to those contacts.

Best Practices
Write compelling subject lines

Keep subject lines under 50 characters. Use personalization: ”, your weekly update is here” outperforms generic subjects by 26%.
Segment your audience
Segment your audience
Don’t blast everyone. Create separate audiences for different interests. Targeted campaigns have 3x higher click rates.
Test before sending
Test before sending
Always send a test email to yourself first. Check links, images, mobile rendering, and variable replacement.
Monitor bounce rates
Monitor bounce rates
Keep bounce rates under 5%. High bounce rates can trigger automatic account suspension. Use email validation to clean your list before sending.
Respect unsubscribes
Respect unsubscribes
Always include an unsubscribe link. Process unsubscribes immediately. This is required by law (CAN-SPAM, GDPR) and improves deliverability.
