How much does OneSignal Email cost?

OneSignal's paid Growth plan starts at $19 per month and includes 20,000 free email sends per month, with additional email billed at $1.50 per 1,000 sends. Pricing applies to the overall platform rather than email alone, and higher volumes and features move to Professional and Enterprise plans. There is no email-only pricing tier.

Does Resend have a free tier?

Yes. Resend's free plan includes 3,000 emails per month, with a limit of 100 emails per day. Marketing usage includes a starting allotment of 1,000 contacts as well. It is aimed at small apps, prototypes, and independent developers.

Can I use OneSignal Email and Resend together?

Yes. Many teams route different message types through different providers or fail over between them. Courier lets you send through both behind a single API and switch providers without changing your code.
