Difference between 'Extended Mail Merge' and 'Standard Mail Merge'

Publish Date: Sep 13, 2023
Description

Available: All Editions
Available: Classic


Mail merge allows you to create word documents where document is tailored to the recipient as though they were sent separately. This is done through mail merge templates which are Microsoft Word documents that contain merge fields. These fields pull in data from Salesforce records thus allowing to you personalize the email you are sending to multiple recipients in one go.

There are two types: Standard Mail Merge and Extended Mail Merge.

 

Resolution


Considerations before requesting Mail Merge


1. Mail merge documents give you access only to the fields that are accessible to you via your Page Layout and Field-level Security settings. Please note that Field-level security is only available in Professional, Enterprise, Unlimited, and Developer Editions.
2. The support for Standard Mail Merge will retire and may not work when Salesforce disables TLS 1.0. Users are strongly encouraged to transition to Extended Mail Merge which supports TLS 1.1.
3. Standard and Extended Mail Merge don't support formatting from rich text area fields.
4. What to do when you encounter Unsupported browser for Mail Merge while on Windows 7, Windows 8 or Windows 10 using Office 2010, Office 2013 or Office 2016.
5. Mail Merge (Standard or Extended) is not supported in Lightning Experience.
