Support questions
What is the fastest way to get help?
Use the contact form below with your workspace, domain, endpoint, and what you expected to happen. For production issues, include the approximate time and affected purpose value.
Where do I open the app?
Use app.sendotp.email to manage the product. The public site keeps docs, pricing, support, and DNS tools available without signing in.
Can support help with DNS and deliverability?
Yes. Start with the DNS checker, then email the domain and provider details if SPF, DKIM, DMARC, MX, or alignment results need review.
Do resend issues usually need a new code?
No. The product contract keeps the same email and purpose on the same active OTP for 10 minutes, so users are not forced to chase newer inbox messages.
