A new application needs more than a send button. It needs a clear path from a local example to a verified domain, a deliberate first message and an email log that explains what happened. Our free launch kit brings those steps together so developers can evaluate Sendar before connecting a real sending account.
Try the workflow before creating an account
The download includes Node.js and Python examples, reusable application-email recipes and a complete local Next.js demo. Start with the welcome recipe or a booking confirmation. The default preview does not contact the email provider and does not need an API key. You can read the request, run the offline tests and decide where the example belongs in your application.
The Next.js example is a development demonstration, not an unrestricted production contact form. Its demo sending route is disabled in production. For a real application, connect sending to an authenticated business event, validate the recipient on the server and protect public forms against abuse. These responsibilities remain with the application developer.
Give your coding assistant concrete instructions
The kit includes a short AI builder guide that points to Sendar’s API contract and describes a preview-first integration. It explains where to store credentials, how to authorize a controlled test and what to inspect after an uncertain response. These are portable instructions for your assistant, not an official integration or endorsement from any AI development platform.
Keep API keys in server-only environment variables. Never paste them into a public repository or a support form. Before sending, create an account, verify your domain and select a recipient you control. A successful API response means provider acceptance, not a guarantee of inbox placement. Inspect the message ID, email log and recipient inbox separately.
Apply for guided setup
We are inviting 10 new projects to a free launch partner pilot covering one project, one domain and one email workflow. Use the application form to describe what you are building, your framework, your planned launch and the obstacle you need help with. We review fit and capacity before confirming a place; submitting the form does not reserve one.
The pilot covers setup guidance and troubleshooting, rather than custom application development. Normal Free plan limits apply: 3,000 emails per month, capped at 100 per day. The free domain checker and starter download remain available without registration, whether or not you join the pilot.
