Send to Winner

Mailing Designer 2 (MD2) features a Send to Winner option when you’ve enabled A/B testing in a mailing (MD2 > Options tab > Envelope tab).

The A and B versions are sent to a percentage of the subscribers, and, after a period of time, the remainder of the subscribers receive the best performing version (if both versions are tied, subscribers receive the A version).

You'll find the Send to Winner options on the MD2 Review & Send tab. You can use Send to Winner with the following schedule options (the Send to Winner features are slightly different for each option):

  • Schedule One-Time
  • Daily or Weekly/Monthly

Schedule One-Time

When you select Schedule One-Time, the Send to Winner delivery method includes the following three fields:

  • Initially Send: Select a percentage of your subscribers to receive the A version and the B version. For example, if you select 10% in the dropdown list, a subset of 10% receives the A version and a subset of 10% receives the B version (there is no overlap).
  • Date Picker: Click the “Then On…” Date Picker to set a date and time to send to the remaining subscribers. For example, if you selected 10% A version/10% B version in the Initially Send dropdown list, the remaining 80% receive the winning version. Informz automatically displays the remaining percentage.
  • Winning Version: Click the dropdown list to select the criterion used to determine the winner:
    • Highest Delivery Rate
    • Highest Open Rate
    • Highest Click Rate
    • Lowest Unsubscribe Rate

Daily or Weekly/Monthly

When you select Daily or Weekly or Monthly, the Send to Winner delivery method includes the following three fields:

  • Initially Send: Select a percentage of your subscribers to receive the A version and the B version. For example, if you select 10% in the dropdown list, a subset of 10% receives the A version and a subset of 10% receives the B version (there is no overlap).
  • Duration: Click the “Then wait…” dropdown list to set a duration after which the mailing sends to the remaining subscribers. You can select between one and seven days.
  • Winning Version: Click the dropdown list to select the criterion used to determine the winner:
    • Highest Delivery Rate
    • Highest Open Rate
    • Highest Click Rate
    • Lowest Unsubscribe Rate

A/B Testing + Statistics = Success!

Being able to easily conduct A/B tests is key for any organization, and it ensures that more successful subject lines, friendly from names, etc. reach your subscribers' inboxes. By using the Send to Winner option, you'll help fine-tune your success. Once you've met your A/B "threshold," only the version that has statistically generated the best results (based on your criterion) continues to send.
