# Sendvo > Sendvo is a self-service direct-mail platform. Teams upload a list, design a postcard, review the credit cost, and click send. Sendvo prints the cards, ships them through USPS, and tracks delivery end-to-end. Mailing is paid with prepaid credits, with the exact cost shown before sending. ## What Sendvo does - **Audience building** - Build a mail audience by drawing a polygon on a map, selecting ZIP codes, picking counties, or choosing entire US states. Niche REI and mortgage list sourcing is also available in-product. Address list uploads are supported. - **Postcard design** - Browser-based postcard editor with templates for common use cases (cash offers, abandoned-cart winbacks, thank-yous). - **Tracked delivery** - Every postcard ships through USPS with tracking events from print to in-home. - **Triggered sends** - Approved account workflows can use business events as mail inputs. Connector, API, and test access must be confirmed for the account. ## Who Sendvo is for Three verticals are explicitly served: 1. **Real estate investors** mailing cash-offer cards on probate lists. 2. **DTC / Shopify brands** winning back abandoned carts with a postcard. See [Ecommerce](https://www.sendvo.io/solutions/ecommerce). 3. **Marketing agencies** running mail for multiple local clients from one dashboard. ## Integrations Sendvo publishes implementation guides for HubSpot, Salesforce, HighLevel, Follow Up Boss, Shopify, Klaviyo, Mailchimp, Zapier, Airtable, Make, n8n, QuickBooks, Stripe, Jobber, ServiceTitan, Typeform, Google Sheets, and generic webhooks. These guides verify source-platform behavior. They do not confirm a native Sendvo connector, public endpoint, field map, or account plan. Confirm the Sendvo connection and non-mailing test path before live use. ## Status Sendvo is **open for self-serve signup**. Create an account at [app.sendvo.io](https://app.sendvo.io/api/auth/sign-up). Existing users log in at app.sendvo.io. The authenticated workspace shows the capabilities available to that account.
