The honest price math

If you mail merge occasionally and only need PDF files on disk, a one-time $59 license is genuinely cheaper than any subscription. MailMergic’s plans buy the delivery layer PlainMerge leaves to you: managed sending from your verified domain instead of configuring your own SMTP, knowing what was delivered, bounced and opened, Word, Excel and image templates, Google Sheets, an API, and a product that ships updates continuously.

Can PlainMerge send the merged PDFs by email?

Yes, through your own SMTP server, which you configure yourself. There is no feedback on delivery, bounces or opens. MailMergic sends over managed infrastructure from your own verified domain and tracks delivery, bounces and opens per recipient.

Which tool handles more template and data formats?

MailMergic works with PDF, Word, Excel and image templates and reads Excel, CSV and Google Sheets. PlainMerge works with PDF templates and .xlsx, .xls or .ods files.

Is PlainMerge related to the old PDF Mail Merger product?

No. MailMergic is the product formerly named PDF Mail Merger; we rebranded in 2024. PlainMerge is an unrelated tool by a different developer.
