In their own words
BetterMerge
BetterMerge sends personalized mail-merge campaigns from Gmail using contacts and merge fields in Google Sheets. Spreadsheet columns can customize subject lines, email bodies, links, images, and attachments, including files from Google Drive. Campaigns can be scheduled with daily limits, sending days, time ranges, and delays. Open, click, and unsubscribe activity is tracked and can be written back to Sheets. BetterMerge lists API access and connects with Gmail, Sheets, and Drive. It says Gmail permission is send-only, without access to read, search, or delete mailbox messages. Its policy says campaign and tracking information plus encrypted OAuth tokens are stored, while Sheets contents, sent email content, Drive files, and Gmail history are not. Data is processed in US-East Hetzner facilities. The Free plan costs nothing and includes 50 emails daily, one sender, up to five campaigns monthly, and open and click tracking. Gmail.com accounts are limited to 500 emails daily on any plan.
Carbone
Carbone merges JSON data into document templates to generate files such as PDF, DOCX, XLSX, and PPTX. Templates can use formats including DOCX, ODT, ODS, XLSX, XML, Markdown, and HTML. Its conversion API handles more than 100 formats and supports LibreOffice, OnlyOffice, and Chromium. API access and bulk generation are listed, with Cloud, On-Premise, Private Cloud, and AWS deployment options. The pricing page lists free Cloud and On-Premise plans, plus a free 30-day trial for self-hosted On-Premise use. Cloud Essential costs $29.00 per month; documents are counted for each 1 MB of injected JSON and images, and additional documents beyond a plan allowance are invoiced separately. Carbone says Cloud stores templates for reuse but does not retain submitted JSON or generated documents beyond what rendering and delivery require. It says it has no access to customer templates, data, or generated documents in on-premise deployments. The service also offers an MCP server and an open-source Carbone Skill for connecting AI assistants and generating templates. Its listed platform options include API, Linux, macOS, self-hosted, web, and Windows.
