The app growth stack

Comparison

Push and lifecycle messaging, compared

APNs will deliver a push for nothing. These exist for everything around it: scheduling, segmentation, other channels, and knowing what happened after it landed.

There is no ranking on this page. Nobody here has run all 5 of these for a quarter, so a score would be invented. What follows is the shortlist, in alphabetical order, with one line on what separates each — and a link to the vendor’s own pricing page, because a price restated here would be out of date before you read it.

  • Braze

    Cross-channel engagement aimed at teams running lifecycle campaigns as a dedicated function.

    Visit sitePublishes no price
  • Courier

    Notification infrastructure behind one API rather than a marketing product — closer to a developer primitive than a campaign tool.

    Visit sitePublishes no price
  • Customer.io

    Lifecycle messaging driven by behavioural data, spanning email, push, SMS and in-app.

  • Iterable

    Cross-channel engagement built around visual journey building.

  • OneSignal

    Push, in-app messaging, email and SMS, commonly the first thing reached for to add push without building the infrastructure.

What you have to check yourself

None of this is knowable from outside, and it is where the decision actually gets made.

  • Apple treats marketing push differently from transactional notifications and requires consent for it separately from the system permission prompt. Read the current guidelines before designing the flow — this page deliberately does not restate them.
  • Who holds your APNs authentication key, and whether you can rotate it without the vendor.
  • How it is priced — per subscriber, per message, or per monthly active user — and what that becomes at ten times your current size.
  • Whether you need the marketing half at all. If the answer is transactional notifications only, this is a large product for a small job.
  • What the SDK collects, because it lands on your App Privacy questionnaire under your name.

Every link on this page was fetched and answered before it shipped, most recently on 2026-09-01. No tool paid to appear here and no link earns anything — see the disclosure page. Missing, wrong, or out of date? Tell us and it gets fixed.
