YourSend is a customer messaging platform for small businesses and developers. It combines capture pages, email and SMS campaigns, automated follow-ups, AI templates, and transactional messaging APIs.

YourSend is built for small business owners who need no-code marketing tools and developers who need email, SMS, OTP, webhooks, logs, and domain infrastructure.

Can YourSend send both campaigns and API messages?

Yes. YourSend supports business dashboard workflows such as blasts, templates, contacts, capture pages, and sequences, plus developer APIs for transactional email, SMS, OTP, and event webhooks.

How much does YourSend cost?

YourSend offers a free tier with 5,000 emails per month and no credit card required. Paid plans start at $6.99/month for Starter, $19.99/month for Growth, and $49.99/month for Scale, with lower per-message rates and additional features at each tier. There are no per-contact fees on any plan.

How do I send an OTP with YourSend?

Send a POST request to /v1/send with the channel set to sms or voice and include the recipient number. YourSend delivers a one-time code automatically. When the user enters their code, POST to /v1/check with the message_id and the code to verify it. The response includes a verified boolean.

Does YourSend support WhatsApp messaging?

Yes. All YourSend plans include WhatsApp as a messaging channel alongside email, SMS, and voice. You can send WhatsApp messages through the same REST API endpoint used for other channels by setting the channel parameter to whatsapp.

Can I use YourSend with my own domain?

Yes. YourSend supports custom sending domains with full SPF, DKIM, and DMARC verification. Messages are delivered under your own domain and brand, so recipients never see the YourSend name. This is included on all plans.

What programming languages does YourSend support?

YourSend provides an official TypeScript/Node.js SDK available as the yoursend npm package, plus a REST API that works with any language. The API uses standard HTTP with JSON payloads, so you can integrate from Python, Ruby, Go, PHP, or any language with an HTTP client.

Answers

Frequently asked questions

What API authentication does YourSend use?

YourSend uses Bearer token authentication. Include your API key in the Authorization header as "Bearer ys_live_..." for production or "Bearer ys_test_..." for test mode.

Can I test the API without creating an account?

Yes. Use the public demo key (ys_public_demo) to send one branded test email or SMS per channel. No signup or credit card required.

Which programming languages are supported?

YourSend provides an official TypeScript/Node.js SDK (npm install yoursend). The REST API works with any language that can make HTTP requests, including Python, Go, Ruby, PHP, and Java.

How do webhooks work?

Configure a webhook URL in your dashboard. YourSend sends POST requests for delivery events including sent, delivered, bounced, complained, and opened. Each event includes the message ID, channel, and timestamp.

Does YourSend support custom sending domains?

Yes. Add your domain in the dashboard, configure SPF and DKIM DNS records, and YourSend verifies them automatically. Messages are sent from your domain, so recipients never see the YourSend name.
