G Merge Plus vs PDFMonkey

G Merge Plus creates personalized documents and email campaigns from Google Sheets. It can combine a sheet with a document template to generate PDFs, Google Docs, or Sheets, then send personalized messages from the user's Gmail address with generated documents attached. Merges can be queued for later or scheduled to recur. Delivery and open reports appear in the Sheet, and the marketing section also describes click tracking. Campaigns can include one-click unsubscribe; opt-outs are recorded in the Sheet and skipped on the next send. Reusable email and document templates are available, with shared templates listed for the Team plan. The workflow includes Gmail, Google Sheets, Google Docs, and Google Drive. G Merge Plus uses Google Sign In and says it does not access Gmail passwords. It says email and generated document contents are not stored, and generated files are kept in the user's Drive. The free plan has unlimited mail merge but no document merge or tracking, and is subject to Google limitations. Pro is $72 a year; Team is $480 a year.

PDFMonkey is a cloud document-generation API that turns templates and dynamic data into files. Templates can be built in a visual drag-and-drop editor or written in HTML, CSS, and Liquid; JSON data can be sent through the REST API to generate documents. Its Chrome-based renderer supports JavaScript, external fonts, images, charts, and other web technologies. Outputs include PDF, PNG, WebP, and JPG, and bulk generation from datasets is supported. Connectors include Zapier, Make, n8n, Workato, Bubble, Glide, and InvoiceBerry; developer tools include Ruby and Node.js SDKs and webhooks. API traffic uses HTTPS/TLS, dynamic data is stored in encrypted database columns, and generated files are kept in private S3 buckets with one-hour presigned URLs. PDFMonkey states that it has no formal SOC 2 or ISO 27001 certification. The free plan allows 20 documents per month with one-day retention and a 30-second generation limit, and excludes external images, fonts, CSS, and JavaScript. Paid plans start at €5/mo.
