Campaigns

Campaigns are one-time or recurring broadcast emails sent to a targeted audience. Use campaigns when you want to send the same message to many contacts at once -- newsletters, product announcements, promotions, or scheduled digests.

Note

For the API reference, see Campaigns API.

Creating a Campaign

  1. Navigate to Campaigns in the sidebar and click "New Campaign"
  2. Name your campaign and choose a sender identity (name, email, reply-to)
  3. Select a template -- choose from your saved email templates
  4. Choose your audience -- select a segment to target
  5. Review the audience preview to see how many contacts will receive the email

Sending Options

Send Now

Sends the campaign immediately to all contacts in the selected segment.

Schedule

Pick a date and time for the campaign to be sent automatically. Scheduled campaigns can be cancelled before the send time.

A/B Testing

Test two variants (different subjects, templates, or sender names) on a percentage of your audience. After a test period, the winning variant is sent to the remaining contacts.

  1. Enable A/B testing when creating the campaign
  2. Configure Variant A and Variant B
  3. Set the test percentage (e.g., 20% gets A, 20% gets B)
  4. Set the test duration (e.g., 4 hours)
  5. Choose the winning metric (open rate or click rate)
  6. Send -- Synapse auto-evaluates and sends the winner

Recurring

Send the same campaign on a schedule (daily, weekly, monthly). Each send creates a new "instance" with its own analytics.

Analytics

After a campaign is sent, view detailed analytics:

  • Delivery metrics: Sent, delivered, bounced, failed
  • Engagement metrics: Opened, clicked, spam reports
  • Rates: Open rate, click rate, bounce rate
  • Recipient list: See the status of each individual recipient
  • A/B results: Compare variant performance (if A/B testing was used)

Best Practices

  1. Always send a test email before launching to verify template rendering
  2. Use segments to target the right audience -- avoid sending to your entire contact list
  3. A/B test subjects to improve open rates over time
  4. Schedule during business hours in your recipients' timezone for better engagement
  5. Monitor bounce rates -- high bounces hurt your sender reputation
