Recently I had some problem when zapier.com entered in action when a client replied to an email – that had Zapier tasks on it. So I found this solutions to make Zapier work only on the original email that you want to work on.
- use unique subjects
- use unique keywords and codes in the body of the email or subject
- make the gmail search using a from: or to: address so you could identify via the email address which is more unique than a subject or email body message
- use the exclusion parameter from Gmail search
Remove messages from your results - Example: dinner -movie
Let me show you my example for Set up Gmail Email Matching Search:
from:(firstname.lastname@example.org) subject:("you're unique subject with unique keywords" -"Re:")
In this example I exclude the replies for that email (that I send), and zapier can do the job!
