Sendo
The best SMS/RCS API for startups
Seoable for Sendo
If you are part of Sendo (or you are a YC founder who looks at Sendo and thinks that is the kind of business I run), you probably do not have time for a six-month SEO agency contract. Seoable was built for that. Audit your site, queue 100 ready-to-publish posts, and run it all from your AI assistant.
About Sendo
We're making it easy, cheap and fun for startups to build on SMS again. Sendo is the most developer-friendly SMS API, with great documentation, a fast dashboard, helpful monitoring features, easier 10DLC compliance and much more. Save 40%+ compared to Twilio and other options, and get started sending messages in 1-2 days instead of waiting weeks for your 10DLC campaigns to get approved.

Founders
Why founders like Sendo use Seoable
- Ship without an agency. Audit your site and queue 100 posts in one afternoon. No briefs to write, no calls to take.
- Drive it from Claude or Cursor. Seoable is MCP-first. Your assistant can run audits, queue posts, and pull reports without you opening a dashboard.
- Pay per piece, not per seat. Credits instead of monthly seats. Buy what you need, when you need it.
- SEO that includes AI engines. Our audits check what ChatGPT, Claude, Perplexity, Gemini, DeepSeek, and Grok already say about you, not just Google.
