Broadcasts
Use Broadcasts for newsletters, product announcements, onboarding sequences, and customer updates. MarkRelay brings the message, recipient data, scheduling, and results into one guided workflow.
1. Create a draft
Start a new broadcast and configure:
- an internal campaign name;
- the sender mailbox and display name;
- an optional separate Reply-To address;
- open and click tracking preferences;
- immediate delivery or a future schedule.
2. Design the message
Begin with a blank message or load a reusable template. Add a subject, preheader, and responsive content with the visual editor. The broadcast keeps its own copy, so you can customize it without changing the source template.
3. Add recipients
Import a .csv or .xlsx file with anemail column. Additional columns—such asfirst_name, company, or plan—can personalize the message. MarkRelay validates addresses, removes duplicates, and lets you review and edit rows before launch.
A single broadcast supports up to 10,000 recipients and 20 custom fields.
4. Preview and test
- Preview desktop and mobile layouts.
- Check the subject and preheader.
- Review personalization with representative values.
- Send a test to your own inbox.
- Check links, images, reply behavior, and the unsubscribe experience.
5. Send or schedule
Launch immediately or choose a future time. The Broadcast list shows preparation and sending progress. You can pause, resume, or cancel an active campaign, and clone a completed campaign when you want to reuse its structure.
Understand results
| Result | What it helps you understand |
|---|---|
| Sent | Messages accepted for outbound sending |
| Opened | Recipients who loaded the tracking pixel |
| Clicked | Recipients who followed a tracked link |
| Replied | Replies connected back to the broadcast |
| Bounced | Recognized failed-delivery responses |
| Unsubscribed | Recipients who opted out from that sender |
Open metrics are directional because some mail clients block or prefetch tracking images. Use clicks, replies, and business outcomes alongside opens when evaluating a campaign.
Send responsibly
- Send only to recipients who expect your email.
- Keep sender authentication and domain reputation healthy.
- Use a recognizable sender and clear unsubscribe option.
- Review suppressions before each launch.
