The first numbers you see when comparing OneSignal and Resend can feel like a battle of the brands, but the real decision hinges on how the money is spent.
The price‑to‑feature ratio
OneSignal’s Growth plan is a single line of $19/month that sits on top of a free tier already capable of sending push notifications. Resend offers a free tier that gives you $0/month for 100 emails a day, 3 domains, and ticket support, an add‑on at $20/month, and a full‑feature Scale plan at $90/month that adds all Pro features, 1,000 domains, and a dedicated [Slack](/entry/slack-vs-github-picking-the-right-tool-for-chat-first-or-code-first-teams) channel. The table below shows the official numbers side by side.
| Vendor | Plan | Price | What you get |
|---|---|---|---|
| OneSignal | Free | $0/month | Basic push notifications |
| OneSignal | Growth | $19/month | Expanded push features |
| Resend | Free | $0/month | 100 emails/day, 3 domains, ticket support |
| Resend | Add‑ons | $20/month | Additional capabilities |
| Resend | Scale | $90/month | All Pro features, 1,000 domains, dedicated Slack |
When you look at the cost per channel, OneSignal’s flat rate is attractive for teams that rely mainly on push. Resend’s tiered approach lets you start at zero and only pay for extra email volume or domain capacity when you truly need it, which can keep early spend low.
Who each plan serves
If your product already has a mobile presence and you need a reliable push solution, the one‑tier structure of OneSignal means you can budget a predictable $19/month and immediately unlock advanced targeting and analytics. For companies building email workflows that may outgrow 100 emails a day, Resend’s free tier is a generous entry point, and the $20/month add‑on keeps the price modest until you reach the 1,000‑domain limit that triggers the $90/month Scale plan.
The choice ultimately comes down to channel focus and growth pace. Teams that need push notifications as a core channel and prefer a single, steady fee will lean toward OneSignal. Startups that prioritize email, want to keep costs low until they hit volume thresholds, and appreciate the option to scale gradually will find Resend’s layered pricing more flexible.
