How to Set Up an A/B Test Email Campaign in Sparkforge

A/B testing in Sparkforge email campaigns lets you compare up to 6 versions of the same email. Pick what to test — subject line for open rate, content for click rate — set the sample size and duration, and Sparkforge sends the winning variation to the rest of your list automatically.

Requirements

• Minimum 10 contacts per variation.
• At least 40 total contacts to run any split test.
• Test duration: 30 minutes to 24 hours.
• Send method: Send Now or Schedule only. Batch and RSS schedules are not supported.
• If no clear winner emerges by the deadline, the first variation wins by default.

Set up the test

Step 1: Enable A/B testing

Go to Marketing > Emails, choose Campaign from the dropdown, and create a new campaign. Toggle on A/B Testing.

Step 2: Choose what to test

• Subject Line — optimizes open rate. Test length, personalization, urgency, curiosity hooks.
• Email Content — optimizes click rate. Test headlines, button copy, layout, images, CTA placement.

Step 3: Set duration

Pick a window between 30 minutes and 24 hours. Long enough for recipients to open and engage, short enough to keep the campaign moving.

Step 4: Set sample size and variations

Use the slider to assign what percentage of contacts get test variations. Up to 6 variations supported. Keep at least 10 contacts per variation.

Step 5: Choose the winning metric

Pick Unique Open Rate (best for subject line tests) or Unique Click Rate (best for content tests).

Step 6: Test, preview, and send

Click the three dots to test or preview. Set delivery to Send Now or Schedule for Specific Date/Time. After send, check enhanced statistics to see per-variation and overall campaign results.
