New

• Locked template versions. When a campaign starts, it keeps the exact version of the template it was started with. Editing the template afterwards doesn’t change emails that are already on their way, and the campaign report shows the version that was sent, with a preview. Your email signature is still added at send time, so signature updates apply.
• Merge tag check before you start. BetterMerge compares the merge tags in your subject, preview text, and body with the columns in your sheet before a campaign starts, and lists any that don’t match.
• Edit a scheduled campaign. Choose Unschedule and edit to move a scheduled campaign back to draft, change it, and schedule it again. The send time you picked is kept.

Improvements

• Campaign reports now count unique opens and clicks: each recipient counts once, however often they open or click. The tracking log still lists every interaction.
• Opens and clicks are recorded more reliably.
