| Sendvo | PostGrid | |
|---|---|---|
| Core focus | Self-serve operator mail | Print & Mail API plus address APIs |
| Who sends | Marketers and operators in a browser | Developers in your application |
| Public per-piece card | Yes — see /pricing | Not published on the pricing page we fetched |
| Audience | Map / ZIP / county / state in-app | Bring your own addresses |
| Designer | Browser editor and proofs | You supply creative to the API |
| Tracking | Per-piece IMb in campaign history | Mail-event webhooks you surface yourself |
| Best for | First send without an engineering sprint | Embedding mail in a product or internal tool |
Where they overlap
Both can print postcards, letters, and other mail once an address and a creative exist. Both can be automated.
The path to that first piece is the difference. Sendvo’s path is a campaign screen. PostGrid’s path is an integration. The same split is written for buyers at dashboard vs API-only and in the commercial table at /compare/postgrid.
Where the workflows diverge
1. Time to first send
Sendvo’s published path is minutes: audience, design, review, send.
PostGrid’s time-to-first-send is your API project. Days to weeks is normal. That is not a knock. It is what an embeddable API costs in calendar time.
2. Pricing you can quote
Sendvo publishes Local, Operator, and Growth rates, including 4×6 at $0.92 / $0.69 / $0.66 and EDDM at $0.65.
PostGrid’s pricing URL is a demo form for Print & Mail API and address verification. Until they publish a public per-piece card, any “PostGrid costs $X” sentence on a blog is a guess. We omit it.
3. Lists and hygiene
Sendvo verifies addresses in the send flow and offers suppression on paid plans.
PostGrid sells address verification as its own API. Hygiene and suppression live in your data layer. That is correct for a platform company. It is extra work for a shop owner.
Where PostGrid stands out (fair is fair)
PostGrid is the better fit when mail is a feature of your software and you already have developers, webhooks, and a recipient store.
International address verification across 245+ countries is a PostGrid product line (PostGrid IAV). Sendvo does not claim that coverage.

Who should choose which
Choose Sendvo if: a non-engineer will send, and you want audiences, proofs, and a published credit total.
Choose PostGrid if: you are embedding print in a product and you will own the integration.
The honest caveats
- This blog vs page and /compare/postgrid cover the same pair on purpose. The compare page is the commercial table. This page is the citable vs article.
- No reply-rate claim is made for either product.
- If PostGrid later publishes a public rate card, update this page from that source. Do not backfill from memory.
Bottom line
Operator dashboard versus mail API. Sendvo for the first. PostGrid for the second.
Keep going with Sendvo vs Lob if you are choosing among APIs, or Sendvo vs Click2Mail if you want another self-service portal. The cluster start page is the best self-service direct mail platform.
FAQ
Is Sendvo or PostGrid better for non-technical operators?
Sendvo. PostGrid is designed for developers embedding mail into software. Sendvo is designed for operators who build audiences and approve proofs in a browser.
Does PostGrid publish postcard prices?
The PostGrid pricing page we fetched on 2026-08-20 is a demo request for Print & Mail API and address verification. It does not list a public per-piece postcard card. We do not invent one.
Does PostGrid include audience building?
No built-in map or ZIP audience browser is claimed here. You bring address data to the API. Sendvo includes map, ZIP, county, and state audiences in the operator UI.
When should I choose PostGrid?
When you need a mail-print API inside your own product, with webhooks and programmatic control. Use the commercial compare page if you want the longer feature table.
