Build it with a little help.
We’re inviting 10 new projects to a free setup pilot. Tell us what you’re building and where email is blocking your launch.
One project. One domain. One email workflow.
Get guided integration and DNS troubleshooting. Share what worked and what got in the way. Applications are reviewed for fit and capacity; applying does not reserve a place.
Request free setup help →Normal plan limits apply. This covers setup guidance, not custom application development or guaranteed inbox placement. Never share passwords or API keys in the form.
Already using an email provider?
Try Sendar in a new project first, or use our migration guides for a controlled transition. A successful API request means provider acceptance; delivery depends on the receiving service and your sending practices.
