This feature allows you to make the lead "jump" to a different part of the automation:
so if you set an IF/THEN where you split an action, as an example if the lead didnt open a mail you resend it,
you can after turn back the lead to the main workflow without creating lots of automations or mirroring the mails of two branches.
Which autoresponder has it?
No Getresponse, No Sendlane, No SendinBlue...
it seems only AC has it.
