Source: https://trysincerely.com/compare/postgrid-vs-click2mail Shortlist PostGrid if your stack needs a separately callable address-verification product, check printing, or named local production networks across the US, Canada, UK and Australia. Shortlist Click2Mail if your team sends varied USPS document types, needs Certified Mail or EDDM, and prefers entry points through office tools, PDF workflows or CRM connectors while keeping an API path open for automation. Neither is exclusively API-only or browser-only; the difference is which adjacent capabilities and interfaces matter more to your operation. ## Where each is the better fit **PostGrid is better** when address data quality and financial documents are central to the program. Its standalone [Address Verification API](https://www.postgrid.com/) handles verification, standardization and autocomplete outside of any print job, which matters if you cleanse lists before deciding what to mail. Checks are explicitly documented as a format alongside letters and postcards. The platform names local delivery networks in the US, Canada, UK and Australia, with plan-level limits on how many networks you can use. **Click2Mail is better** when your team lives in documents and needs USPS-specific products without managing separate vendors. Its catalog includes [Certified Mail](https://click2mail.com/by-product/certified-mail/certified-letter-8-5-x-11), Priority Mail, Priority Express and [EDDM](https://click2mail.com/) for neighborhood saturation without purchasing addresses. Entry points span [Online Pro](https://click2mail.com/), Word and Google Docs add-ons, PDF-to-mail workflows, email-to-mail and CRM [Connect](https://connect.click2mail.com/) for Salesforce, Podio and Follow Up Boss. The [REST API](https://developers.click2mail.com/docs/getting-started) supports both production and staging environments with the same capabilities as the website, so you can start in a browser and automate later without switching platforms. ## Pricing commitments and postage conditions PostGrid’s [$0/month Starter plan](https://www.postgrid.com/pricing-print-mail/) charges for every piece mailed and allows up to 500 mailings monthly before overage fees apply. It includes one user and one local delivery network. Enterprise adds unlimited users and two or more networks. US Starter rates for a black-and-white First-Class letter run $1.059 and color First-Class $1.219, though exact quotes depend on pages, postage class and destination. Its [standalone address-verification plans](https://www.postgrid.com/address-verification-software/costs-pricing/) are priced separately: US/Canada Essential is $20/month for 2,000 lookups, or $18/month with annual billing. International verification has separate pricing. Click2Mail advertises [no subscription fees and no minimum volume](https://click2mail.com/). You pay per job based on printing, postage and optional extras. The [estimator](https://click2mail.com/by-product/certified-mail/certified-letter-8-5-x-11) breaks out pages, color, print option, envelope, production time, mail class and optional return receipt. A displayed starting price is not a universal per-piece rate; run your specific format through the estimator or request a quote matching page count, envelope type and postal service.

Check the selected postal service’s delivery terms separately. The sources reviewed here do not establish a complete format-by-format comparison: if Certified Mail is essential, confirm its availability with PostGrid; if checks or standalone verification are essential, confirm those with Click2Mail. Inspect API rate limits, event retention and cancellation cutoffs in each vendor’s documentation and test environment before migrating. ## One practical way to decide Build the same test mailing in both environments: a multi-page letter with representative test addresses, preferred postage class and proof requirements. Use separate small recipient lists for any live samples. Inspect how each platform handles validation failures, retry logic and status events. Request matched quotes for your volume, format and destination, and ask to retain a sample artifact. Confirm with each vendor which destinations they cover and how long your application can access send history and tracking events. ## How Sincerely fits Sincerely also serves named-account B2B mail with copy grounded in researched account facts, approved design and explicit human launch before anything prints.
