Email marketing and its algorithm for sure detects the same content in "sales" email and will be marked as spam, this will help our emails vary from every email we sent in a drip.
Example:
Hi John,
I hope that you're doing well. I'm trying to reach you earlier and you missed my phone call. {{Are you available later today? | Does 4 or 5 PM works? | Can I call you back later today?}}
---
As you can see in this example you have 3 options.
For a birthday, any occasion, or event greetings workflow. This will be really helpful and create multiple contents in one go and have different greetings send out.
