Last updated on Oct 18, 2025

Hey there ๐Ÿ‘‹๐Ÿป,

SalesBlink gives you the option to A/Z test ๐Ÿงช multiple variants of your cold email templates to help you find out the best performing cold email.

It's super easy to set up & helps you to find the winning cold email copy ๐Ÿ“ง.

Here's How๐Ÿ‘‡๐Ÿป

While creating a sequence, add a Cold Email block, then click "Enable A/Z Testing".

You'll see two options under A/Z Testing

๐Ÿค– AI Distribution

Let AI select your winning email template & automatically send to your leads in the sequence.

  1. Select multiple email templates.

  2. Select your winning metric, this is the metric based on which AI will decide the winning cold email template.

  3. Set a percentage to A/Z (recommended 10%) - This will set the percentage of leads the AI will send emails to before checking the winning metric and deciding the winning email template.

๐Ÿš€ Once AI decides the winning email template based on your settings, the other leads (apart from the percentage of leads used to A/Z Test) will receive the winning email template.

Note: If you are selecting winning metric Reply, Opens or Link Clicks - make sure tracking is enabled while scheduling the sequence.

๐Ÿง‘๐Ÿปโ€๐Ÿ’ป Equal Distribution

When selected, the email templates will be equally split among the number of leads that reach this step in the sequence.
