Yes – Streak's snippet functionality is compatible with our mail merge tool!
Start a Mail Merge from a compose window
Compose your message and include the variables you're looking to incorporate into the snippet.
When you're finished, select the Snippet button from the Compose window's toolbar.
Select Create snippet from draft, fill in the details required for a snippet, and select Create.
This snippet will now be available to use across your Streak account. Please note that your mail merge's variables will only be useful in a mail merge. Adding variables to an email outside of a mail merge will not include the text or value of those variables.
