Mass Mail Merge can be used to create and send personalized mass mail that will incorporate data from the EspoCRM instance. The feature works by generating the mail merge PDF file based on a predefined template for a certain target list of recipients. In other words, it allows businesses to create a single PDF document with personalized letters for mass snail mailing that include recipients’ personal data (such as name, address, phone number, etc.). By doing so, companies can print out and send highly personalized promotional messages in postcards, letters and leaflets. Mass mail marketing initiatives help increase brand awareness and present give the opportunity to differentiate the business from its competitors.
