Here is the honest path, route data through Salesforce, HubSpot, or a CSV, and let Sincerely take it from there. Source: https://trysincerely.com/integrations/zapier There is no Sincerely app in Zapier today, so you cannot add Sincerely as a step in a Zap. That is the whole answer to "does Sincerely integrate with Zapier": not natively, not yet. But you do not need one to make the two work together. Zapier is already good at moving data into places Sincerely reads natively: [Salesforce](https://trysincerely.com/integrations/salesforce), [HubSpot](https://trysincerely.com/integrations/hubspot), and [CSV files](https://trysincerely.com/integrations/csv). Point your Zaps at one of those, and Sincerely picks the data up from there. ## Prompt to paste into your agent ```text My Zap writes new contacts into the Salesforce list view called Q4 tier 1. Add that list view to the Sincerely sync scope, check sync health and mailing addresses, tell me which records need review, and stop before approving or sending anything. ``` ## The honest paths Sincerely's native integrations are Salesforce, HubSpot, CSV import, and an MCP server. Zapier connects to [more than 9,000 apps](https://zapier.com/apps), including the first two. So the bridge is simple: use Zapier to land your data in a system Sincerely syncs from. ### Path 1: Zapier to your CRM to Sincerely This is the best path for most teams. 1. Build a Zap that writes to Salesforce or HubSpot. For example: a demo request in Typeform creates a HubSpot contact, or a webinar registration in Zoom creates a Salesforce contact. Sincerely syncs contacts, not leads. 2. In Salesforce, have the Zap set a field you can filter on, and build a Contact list view on that field. Add the view to Sincerely's Salesforce sync scope. New records flow in on the next sync, which runs every 15 minutes. HubSpot has no list or property filter to aim at. The sync reads every contact in the portal once a day, so new contacts arrive on their own if the Zap associates each one with a company. You narrow the audience inside Sincerely, for example by contact owner. The upside: Sincerely gets full CRM context, not just a name and address. Every piece is written for one recipient from that context, so richer records mean better mail. ### Path 2: Zapier to a CSV to Sincerely If the data never touches a CRM, collect it in a Google Sheet or Airtable with Zapier, then export a CSV and import it into Sincerely. This is a manual step, so it fits batch sends better than always-on triggers. Sincerely resolves imported addresses and checks mailability before printing, so a scrappy spreadsheet is a fine starting point. ### Path 3: The MCP server, the programmable path If you want automation without a CRM in the middle, Sincerely runs an MCP server at `https://trysincerely.com/api/mcp`. Any MCP agent, Claude Code, Cursor, or others, can build audiences, write pieces, and prepare campaigns against it. This is the closest thing to a direct API path today. One guardrail never moves: anything that prints or spends money shows a human a confirmation card first. See [MCP agents](https://trysincerely.com/integrations/mcp-agents) for setup. ## What each path trades | Path | Best for | Tradeoff | | ------------- | ------------------------------ | --------------------------- | | Zapier to CRM | Ongoing triggers, rich context | Needs Salesforce or HubSpot | | Zapier to CSV | One-off lists, no CRM | Manual export step | | MCP agent | Programmatic workflows | Needs an MCP-capable agent | ## When Zapier alone is the better tool If your goal is instant, fully automated mail on every trigger with zero review, Zapier plus a print API like Lob does that today, and Sincerely does not. Lob's [Zapier app](https://zapier.com/apps/lob/integrations) ships Send Postcard, Send Letter, and address-verification actions, so a Zap can mail a piece with nobody reading it first. Sincerely holds the first ten researched pieces for review, and a draft that leans on a thin or unsourced claim always waits for a person. Clean copy can auto-approve after that. If you want fire-and-forget postcards, use the API route. If you want mail that reads like a person wrote it, measured against [holdouts](https://trysincerely.com/holdout-testing), the paths above get you there. ## Will there be a Zapier app? A dedicated Zapier app may come later; none exists today. For the usual workflow, the CRM bridge takes about ten minutes to set up and keeps the trigger visible in the system the sales team already trusts. That is generally less fragile than passing a half-described contact directly from one automation to another. Let Zapier move the source data into the CRM. Sincerely can take over when the account is ready for a researched piece of mail. ## Related questions - [Salesforce direct mail: automate mail from your CRM](https://trysincerely.com/integrations/salesforce): Sync accounts and contacts from Salesforce, write each piece from CRM context, approve before anything prints, and time rep follow-up to confirmed delivery. - [HubSpot direct mail: automate mail from your CRM](https://trysincerely.com/integrations/hubspot): Sync contacts, companies, and properties from HubSpot, write each piece from CRM context, approve before anything prints, and time follow-up to delivery. - [Direct mail from a CSV](https://trysincerely.com/integrations/csv): CSV import is a native Sincerely integration.
