Sincerely runs measured B2B direct mail campaigns. Which fits depends on what you need mail to do. Source: https://trysincerely.com/vs/ignitepost Pick IgnitePOST if you want robot handwritten cards mailed automatically, especially for ecommerce thank-yous and review requests. Pick Sincerely if you run B2B outbound and need handwritten notes, postcards, and letters written per recipient, with holdout measurement, so you can prove the mail moved pipeline. One honesty note up front: Sincerely mails handwritten notes to US addresses, and it does not write them itself. Handwrytten's pen robots do, under Sincerely's plan pricing. So if a handwritten card is all you want, buying a handwriting vendor direct is cheaper and simpler. The rest of this page is about what Sincerely adds around the card. ## Quick comparison | Dimension | IgnitePOST | Sincerely | | ----------------- | ------------------------------------------------------------ | ------------------------------------------------------------------- | | Core product | Robot handwritten cards in real ink | Handwritten notes, postcards, and letters for B2B outbound | | Who it serves | Ecommerce, insurance, real estate, nonprofits, sales teams | B2B sales and marketing teams | | Personalization | Merge fields into a card template | Each piece written for one recipient from CRM context | | Audience building | You bring the list | CRM sync, CSV, or Sincerely finds businesses and verified addresses | | Measurement | Delivery tracking; attribution is on you | Locked experiment design, holdouts, lift with confidence intervals | | Integrations | API, Zapier, Shopify app, Klaviyo webhooks | Salesforce, HubSpot, CSV, MCP server for agents | | Entry price | Prepaid cards from $1.75 each; subscriptions from $109/month | $199 one-time pilot, 100 pieces included | ## Where IgnitePOST is the better choice Recommending the right tool matters more than winning the page, so here it is plainly. - You want a handwritten card and nothing around it. IgnitePOST writes cards with robots holding real pens, in over 12 handwriting styles, with handwritten envelopes. It will also mimic your own handwriting. Sincerely mails handwritten notes too, but through Handwrytten, with a platform above it. If the card is the whole job, buy a card vendor direct and skip the layer. - You run ecommerce lifecycle mail. Abandoned cart recovery, review requests, and VIP thank-yous triggered from Shopify or Klaviyo are IgnitePOST's home turf. Sincerely has no Shopify or Klaviyo integration. - You want Zapier triggers. IgnitePOST has Zapier and an API. Sincerely has no Zapier app; the honest bridge is CRM sync, CSV, or an [MCP agent](https://trysincerely.com/integrations/mcp-agents). - You send the same short message to many people. A thank-you card does not need account research. Paying for per-recipient writing would be waste. - Your list is consumers, not businesses. Sincerely's audience engine finds businesses and business addresses. Consumer lists are not its job. For more on when the handwritten format itself earns its cost, see [handwritten mail for B2B](https://trysincerely.com/guides/handwritten-mail-b2b). ## Where Sincerely wins Sincerely is built for a different problem: getting B2B buyers to respond, and proving it worked. - Writing, not mail merge. Every piece is drafted for one recipient from CRM context and researched account facts, and a human approves it before anything prints. IgnitePOST fills merge fields into a template you wrote once. - Audience building. Describe your ideal customer and Sincerely finds the businesses and USPS-verified addresses. With IgnitePOST, list building and address quality are your problem. - Measurement you can defend. Campaigns lock a primary outcome, a window, and a holdout percentage at launch. Readouts show lift against account-level holdouts with confidence intervals, and say plainly when a result is not statistically ready. See [how measurement works](https://trysincerely.com/measurement). IgnitePOST tells you the card was delivered, and its site mentions attribution, but it publishes no holdout or incrementality method, so proving cause is left to you. - Address hygiene by default. Every address is resolved, scored, and USPS-verified before printing, and suppression is immediate and global, on every plan. - Agent access. Sincerely is an MCP server, so Claude Code, Cursor, or any MCP agent can build audiences and draft campaigns. Anything that spends money still requires human confirmation. ## Pricing reality IgnitePOST, as of August 2026, per their [pricing page](https://www.ignitepost.com/pricing): prepaid cards run $1.75 to $4.39 each depending on volume, and subscriptions run $109 per month (300 cards per year) up to $1,744 per month (6,000 cards per year). Prices include stationery, a handwritten envelope, the card, and First Class postage. Enterprise pricing is custom. Two caveats: the page does not publish the volume thresholds behind each prepaid rate, and the subscription figures are annual rates, so monthly billing goes through sales. Sincerely: a $199 one-time pilot covers 100 pieces with everything included. Monthly plans run from Core at $250 per month (150 pieces included) through Scale at $3,500 per month (3,700 included). Past included volume, 4x6 postcards cost $1.75 down to $1.00 per piece by tier, and letters $2.00 down to $1.25, print and postage included. Handwritten notes are priced per card on your plan, and that rate falls at every plan step; the app shows the exact number for your plan. There is no per-seat pricing, and unused pieces roll over up to one extra month. Full details on the [pricing page](https://trysincerely.com/pricing). The per-piece numbers look similar, but you are buying different things. An IgnitePOST card is a handwritten format with your template message. A Sincerely piece is researched, individually written, human-approved, and measured against a holdout. New Sincerely workspaces also start on a free audit plan: connect a CRM, check mailability, and draft pieces before paying anything. ## The decision rule Ask what the mail has to do. If it just has to look handwritten, or fire automatically from ecommerce events, use IgnitePOST. If it has to open B2B accounts, in whichever format fits each account, and you have to prove the lift to whoever pays for it, use Sincerely. Buy IgnitePOST for the ink. Buy Sincerely for the campaign that decides who gets the ink, and the evidence it worked. --- Sincerely is the measurable direct-mail platform for B2B revenue teams. One workflow. One invoice.
