Contacts and properties sync in, follow-up tasks fire on confirmed delivery, and every piece is written from your CRM context. Source: https://trysincerely.com/integrations/hubspot Sincerely has a native HubSpot integration. Connect your portal, and your contacts, companies, and properties flow into Sincerely as audiences. When a piece is confirmed delivered, Sincerely raises a follow-up task so your rep calls while the mail is still on the desk. No Zapier, no CSV shuffling, no middleware. The shape is simple: HubSpot data in, follow-up tasks timed to real delivery. ## What syncs in - **Contacts and companies.** Sincerely pulls the contacts and companies in your portal and refreshes them on a schedule, so a record that newly matches your audience filters gets picked up on the next sync. - **Properties.** Contact and company properties come along: name, title, company, lifecycle stage, deal stage, owner, and any custom property you use for segmentation. - **Context for writing.** Sincerely writes each piece for one recipient. Properties and researched account facts feed that draft, and a human approves it before anything prints. Addresses get resolved, scored, and USPS-verified before anything prints. Most HubSpot contact records have no verified mailing address, and that is fine. Sincerely finds and verifies business addresses as part of the audience build. [Address verification](https://trysincerely.com/guides/address-verification-explained) is included on every plan. ## How follow-up timing works Sincerely does not write to HubSpot. Instead, when the print vendor confirms a piece was delivered, Sincerely creates a follow-up task on its own side, due the next day. The rep sees "postcard landed Thursday, call Friday" instead of guessing, and the timing comes from a real delivery event rather than an estimate. ## Trigger examples that work today Use a property filter as the trigger. When a contact starts matching it, they enter the audience on the next sync. Concrete examples: - **Deal stage moves to "Demo scheduled".** Mail a pre-meeting piece so it lands before the call. - **Lifecycle stage hits MQL, but sequences get no reply.** Route dark accounts to mail after 14 days of email silence. - **Deal closes lost with reason "timing".** Enter a [closed-lost revival](https://trysincerely.com/playbooks/closed-lost-revival) audience 90 days later. - **A target account's contact attends your webinar.** Follow up with a piece referencing the session, landing within a week. - **Renewal date is 60 days out and health score drops.** Mail the champion before the renewal call. Any contact or company property you can filter on in HubSpot can define an audience in Sincerely. ## Measurement stays honest Campaigns lock an experiment design at launch: primary outcome, window, and holdout percentage. Readouts report lift against account-level holdouts with confidence intervals, and say plainly when a result is not statistically ready. CRM matchback against HubSpot deals is labeled as inference, QR scans as evidence. Details on the [measurement page](https://trysincerely.com/measurement). ## What this is not - Not a HubSpot workflow action. You define audiences in Sincerely from HubSpot properties; you do not drop a "send postcard" step into a workflow today. - Not a write-back into HubSpot. Sincerely reads your portal and never edits it. Follow-up tasks live in Sincerely. - Not gifts. Sincerely mails 4x6 and 6x9 postcards and letters printed through Lob, postage included, plus handwritten notes to US addresses. Gifts have no live fulfillment today. - Not a fire-and-forget blast. Every piece gets human approval before it prints, and suppression is immediate and global. ## Getting started 1. Create a workspace. New workspaces start on a free audit plan, no card required. 2. Connect HubSpot and filter the contacts you want to reach. 3. Audit mailability: Sincerely scores how many contacts have verified, mailable business addresses. 4. Build the brand kit and draft pieces. 5. Choose a plan when you are ready to mail. Pilot is $199 one-time for 100 pieces, all included. Full tiers are on the [pricing page](https://trysincerely.com/pricing). Nothing can be mailed until you pick a plan, so the audit costs you nothing but the OAuth click. Your HubSpot contacts go in, a verified piece of mail goes out, and a task tells your rep the exact day it landed. --- Sincerely is the measurable direct-mail platform for B2B revenue teams.
