Source: https://trysincerely.com/alternatives/postgrid [PostGrid](https://www.postgrid.com/) runs print-and-mail APIs for letters, postcards and checks, with standalone address verification and documented paths for Salesforce, HubSpot, Zapier, Marketo and QuickBooks. Its [Starter plan](https://www.postgrid.com/pricing-print-mail/) costs $0 monthly, with per-piece fees and a 500-piece allowance before overage fees apply, one user seat, and one local delivery network included; Enterprise adds multiple networks and additional seats. The platform advertises processing and carrier handoff within two business days, which is not a delivery guarantee. Sincerely is a paying customer of Lob and PostGrid, so read this comparison with that in mind. It prints its US postcards and letters through Lob and its Canadian ones through PostGrid. Teams consider alternatives for different reasons. Some want a different campaign workflow. Others need B2B account research and experiment design bundled with physical sending. A few require gifting or more complex fulfillment operations. These five alternatives address those specific situations. | Alternative | Best for | Pricing, October 2026 | Where it beats PostGrid | | ----------- | -------------------------------------------- | --------------------------------------------------------------------- | -------------------------------------------------------- | | Lob | Campaign tools on top of mail infrastructure | Free Developer tier, postcards from $0.905; Startup from $260 a month | Campaign tools and deeper webhook events next to the API | | Postalytics | CRM-triggered campaigns | Free plan; Marketer $199 and Pro $399 a month, plus pieces | Mail triggered from HubSpot or Salesforce without code | | Stannp | A plain platform with many connectors | Free plan, 4x6 postcard $0.86; $0.80 to $0.72 on the $12 Starter plan | 1,000+ advertised integrations through Zapier and Make | | PFL | Complex formats and fulfillment | Quote only | 25+ mail formats, kitting, and storage | | Sincerely | B2B account campaigns | $199 one-time pilot; plans from $250 a month | Research, per-recipient writing, and holdout measurement | ## Lob: integrated campaign tools and mail infrastructure [Lob](https://www.lob.com/) is the closest swap: another print-and-mail API with a free tier. As of October 2026, its [Developer plan](https://www.lob.com/pricing) allows up to 6,000 mailings a year with postcards from $0.905, against PostGrid's $0.902 First-Class 4x6 on Starter, so price is close to even at low volume. Lob differs in its campaign tools beside the API and its webhooks that carry USPS tracking events. It also treats Canada as [international mail](https://help.lob.com/print-and-mail/building-a-mail-strategy/international-mail), with First-Class postage only and no tracking past the last US scan. If a real share of your list is Canadian, test that path with a few live addresses before you move. See [Lob vs PostGrid](https://trysincerely.com/compare/lob-vs-postgrid). ## Postalytics: CRM-triggered campaigns with event feedback [Postalytics](https://www.postalytics.com/direct-mail-integrations/) connects to HubSpot, Salesforce, ActiveCampaign, Klaviyo and other marketing tools, with delivery and response events returned to source systems. Its [pricing](https://www.postalytics.com/direct-mail-pricing/) puts Salesforce integration and multi-touch Flows automation on Pro and Agency plans; the Marketer tier excludes them. For teams already managing audiences in a CRM, this provides a documented path to trigger mail without custom API development. Verify your required trigger, field mapping and attribution event are available on your target plan before committing. ## Stannp: straightforward platform with connector flexibility [Stannp](https://www.stannp.com/us) provides a direct-mail platform with a custom API and third-party integrations for teams with an existing audience. The vendor documents over 1,000 connections, though these are third-party rather than all native. Compare the precise connector path for your CRM or warehouse against your current PostGrid integration, and evaluate total per-piece cost including any subscription against PostGrid's usage-based model. [Stannp's full price grid](https://trysincerely.com/guides/stannp-pricing) shows which monthly plan unlocks each piece rate. ## PFL: complex formats and fulfillment with CRM journeys [PFL](https://www.pfl.com/) combines technology with in-house printing, storage and fulfillment across 25-plus mail formats, supporting batch sizes from hundreds to millions. Its [triggered journeys](https://www.pfl.com/solutions/marketing) map CRM and marketing automation data into variable templates, with attribution reported back to the source system. This addresses requirements beyond standard letters and postcards: dimensional mail, kitting and inventory operations where PFL handles physical production and storage. Consider this route when enterprise journey orchestration with Salesforce, Marketo or Oracle is already in place, or when the program requires complex physical fulfillment. ## Sincerely: B2B account campaigns with research and measurement [Sincerely](https://trysincerely.com/) serves teams running [B2B direct-mail campaigns](https://trysincerely.com/personalization) for named accounts, where each recipient's copy draws from CRM data and researched account facts rather than template variables alone. A person confirms the audience, design, campaign rules and spend before launch. The product includes [account-level holdouts](https://trysincerely.com/holdout-testing) with confidence intervals for estimating incremental lift, plus hosted landing pages and response links for printed pieces. [Gifts](https://trysincerely.com/gifts) require a recurring plan with separately prepaid gift funds in addition to mail credits. Handwritten 4x6 postcards and letters are genuinely written by hand, within a daily writing capacity. This is not a replacement for PostGrid's API or transactional mail use cases. Sincerely does not expose a raw transactional print API and fits when the work of identifying accounts, researching context, writing per-recipient copy, and designing account-level experiments is central to the program. ## When staying with PostGrid is better PostGrid remains appropriate when the workload centers on transactional formats like checks or invoices, when standalone address verification must stay available independent of sending, or when the engineering team has already built around its API and event model. The Starter plan's $0 base cost with per-piece fees suits low or unpredictable volumes. A migration carries template, webhook handling and retry logic costs that may outweigh marginal feature gains. ## A practical evaluation step Name the limit you hit. If it is the 500-mailing monthly cap on Starter, a second delivery network, or a second user seat, the fix may be a PostGrid Enterprise quote rather than a new vendor. If the problem is the work around the mail, such as targeting or campaign setup, pick the alternative built for it. For an API move, send the same 50 test letters through each sandbox, including a bad address and a request sent twice by mistake, and compare what each API returns. Then mail a small live batch to a list nobody else is mailing that week, so no one gets the same letter twice. ## Related questions - [Sincerely vs PostGrid](https://trysincerely.com/vs/postgrid): PostGrid is a print-and-mail API for developers.
