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. 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. ## Lob: integrated campaign tools and mail infrastructure [Lob](https://www.lob.com/) offers direct-mail campaign tools, APIs, and print-network infrastructure. The practical difference lies in workflow ownership: evaluate which platform's template system, webhook handling, and retry behavior match your team's required campaign controls. Both provide APIs; compare their specific implementations rather than assuming functional equivalence. ## 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. ## 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 sending is not open yet. Check current availability before switching a handwriting program. 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 Before switching, isolate the actual friction: monthly volume limits, network geography, integration setup, or campaign management requirements. Map that need to one alternative's documented strength. For API-dependent workflows, test error handling, idempotency and address failure behavior in a sandbox environment first, then run a controlled live sample with a separated audience segment rather than duplicating sends to the same recipients. For platform migrations, verify your required trigger, field mapping and attribution event survive the move. Check current pricing and network coverage for your specific destinations, as terms may have shifted since your initial implementation. ## Related questions - [Sincerely vs PostGrid](https://trysincerely.com/vs/postgrid): PostGrid is a print-and-mail API for developers.
