In this article, you will learn how your emails are processed and sent with Yet Another Mail Merge.
How is your email being sent out when using YAMM?
1. YAMM sends an instruction to Gmail
YAMM will only use your Google account to send a specific instruction to Gmail (ie: 'Send multiple emails'). Technically, it's as if you were the one sending this request.
In other words, YAMM only fetches data from your Google Sheet, and transfers it to Gmail / Google servers.
2. Gmail gets the instruction and sends your email
After getting our YAMM instruction, Gmail will send an email with your Google account to all recipients from your Google Sheet, as if you were sending them manually from Gmail interface.
So the fact that YAMM lets you send mail merges doesn't mean that we are sending emails for you. Gmail is still the unique tool that sends and delivers your emails in bulk.
*The only exception is the use of our Salesforce connector, which requires an extra permission from user side.
Which technology do we use to send your mail merge?
Yet Another Mail Merge relies fully on Google Apps Script technology to do main actions like:
- Access data from your spreadsheet
- Import recipient list from Google Contacts
- Send your mail merge
All your emails are actually sent from your own Google account to your recipients, and only via Google servers. YAMM doesn't have access to your Google account, as the authentication requires a security action from user side (password, 2-Step Verification etc.) which is directly managed by Google.
What happens to my data after a mail merge completes?
Once Gmail finished to send your emails to your contact list, all your emails are stored only in your Gmail box. At no time are we storing a copy of your emails.
Besides, all your recipients' email addresses also stay in your own Google Sheets. Unlike other ESP like MailChimp, from YAMM side, we do not store any of your spreadsheet information in an external database.
