[Experience] Using Postmark to send tonnes of email instead of Gmail

Hellos
Just sharing my experience, when sending broadcast emails to client or even to internal office , google keeps limiting the number of emails to be sent via their services . 

Enter Postmark , we are on a legacy plan $10 a month which allows to send 10,000 emails which are 3x of what we needed. Everything's authenticated properly and no limits. 

With ETL - no pause is required between loop & send email actions to 'cool down' 

Hope this helps others.
