Notifications Landscape

What Siri AI means for your email, SMS, and push

Siri AI shipped with iOS 27 and changes what happens to a message after it's delivered. It reads urgent notifications aloud, searches Apple Mail and Messages, can delete or unsubscribe from your email on request, and will soon answer "where's my order?" through apps. Here's what each change means for your email, SMS, and push, and what to do now.

A marketer's guide to iOS 27 and priority notifications

On iOS 27, Apple Intelligence ranks and silences push notifications, rewrites them into summaries, and reads urgent ones aloud. Mail sorts your email into categories, Messages screens texts from unknown numbers, and Gmail, Slack, and Teams add their own filters on top. Here's what each layer does, what you can control, and what to change this quarter.

WhatsApp Business messages: types, templates, and rules

Every WhatsApp Business message is a template or a free-form message, and the type decides when you can send it and what it can look like. How businesses use each one, the template categories, the formats worth knowing, and the rules that stop messages from arriving.

WhatsApp pricing changes on October 1, 2026

On October 1, 2026, two things become billable on the WhatsApp Business Platform: free-form replies inside the 24-hour customer service window, and utility templates sent in response to a customer. If your WhatsApp volume is conversations rather than campaigns, this is not a rate tweak. It adds a line to your invoice where there used to be a zero. Here is what changes, a worked example of the cost, and what to check.

Clinical alert and notification systems: how escalation works

A clinical alert is easy to send and hard to close. This is how alerting works inside a hospital: where alerts come from, how routing by role and shift works, and how the acknowledge, timeout, escalate loop is actually built, including what happens when nobody answers.

Courier vs Customer.io: 2026 customer messaging comparison

Courier and Customer.io both send across email, push, SMS, and in-app, but they are not priced or built the same way. Courier bills by the send, puts journeys, experiments, broadcasts, an in-app inbox, preferences, and 50+ delivery providers on one platform, and exposes all of it through an API, a CLI, and an MCP server. Customer.io bills by the number of profiles in your database and is built around marketing campaigns. This comparison covers pricing, journeys, channels, in-app messaging, localization, and preferences, with every competitor figure taken from Customer.io's own pricing page and docs.

Email preview tools compared: 6 that render on real devices

Most "email preview" features are simulations. These six open your email in the actual client and send back a screenshot. Here’s what each costs per preview, how much work sits between your template and the result, and which ones you can drive from code.

A developer's alternative to Intercom for product notifications

Intercom renamed itself Fin and agreed to be acquired by Salesforce, both around its AI support agent. If you're using it to send your product's notifications, it's fair to ask what the platform was actually built for. Its API answers the question: there is no push or SMS send endpoint, and the campaign builder has no API at all. Here's the architecture, the cost math, and how to migrate transactional and marketing sends.

Top 11 push notification platforms compared for 2026

Push starts as the whole job, then product wants an email fallback, legal wants a preference center, and support wants a searchable log. This guide compares 11 push notification platforms on channels, free tiers, and pricing, and shows why Courier's single API for push, email, SMS, in-app inbox, Slack, and Microsoft Teams fits that arc better than a push-only tool. Includes Airship's 2025 opt-in and open-rate benchmarks, a full-stack cost comparison, and what each platform leaves you to build.
