Communications
Email, inbox, web push, and mobile push in one composer. Choose the Conversion that matters, run the Experiment, and see which Variant won.
No credit card to start.
Communications + Experiments
Write the Control and Variant side by side, choose the Conversion that matters, and run the Experiment in the same place.
Apex shows the Winner and puts a dollar value on the difference. You do not have to match a send report to an experiment report later. The message and its Outcome stay together.

Set up Apex Communications
Add Apex MCP to Cursor with one click. Your coding agent can then find the signup, cart, purchase, and product moments already in your code, match their customer details, and check that they are arriving.
Start with a complete message, then change every word in the Communication Composer. Each message shows the customer details it needs, and the preview merges example values before it sends. Preview email, inbox, web push, and mobile push before you send.

Themes + inbox previews
Set fonts, sizes, colors, buttons, and dark-mode behavior in one Theme. Preview the Theme in Apple Mail, Gmail, Outlook, and Yahoo, in light and dark.
Apex names the inbox and the problem when a color choice may not hold up.

In dark inboxes, Apex darkens your surfaces on-brand and lightens text so the email isn't glaring.

Marketing Campaigns
Choose the Segment, schedule, communication, Conversion, and conversion window for a Marketing Campaign in one place.
A launch announcement is not successful because someone opened it. Choose the Conversion that counts, then see whether customers did it.

Adoption Milestones for product-led growth
Pick the product moment that matters: invite a teammate, publish a project, or enter a paid tournament. Turn any valuable product action into an Adoption Milestone. Apex shows who is Not yet and who is Done, then sends a Nudge before completion and a Celebration after it.
The Nudge stops the instant a customer becomes Done, and a Global Holdout shows whether it caused more customers to finish. That turns product-led growth from a funnel you watch into a path you can improve.
One Milestone. Both outcomes.

Keep the lesson
When an Experiment ends with a clear Outcome, Apex offers to save it as a Belief. You choose whether to keep it. The next message starts with what you already know.

Your move
Start with a template, make it yours, and run the first Experiment against a Conversion you already track. You do not need a sales call to begin.
