Email is read days after it’s sent. What’s in it should still be right.
Alterable is an open-time email content platform for email marketers and agencies. It draws the countdown, the product and its price at the moment each email is opened, not the moment it was sent.
Sent Monday morning. Opened Thursday at 8:40 pm.
Why Alterable exists
Movable Ink made open-time email content a category, and the idea was obviously right. It is sold as programmatic CRM to enterprise teams: no published pricing, a demo, then a sales process.
Alterable exists to put the same idea within reach of any team that sends email, with a free plan, published prices and nothing to install. How the two compare

What makes Alterable different
Published prices, no contract
Free has every service but local maps and 5,000 impressions a month, no credit card. Starter is $19 a month, Pro $79 and Scale $299, billed monthly or annually, and you can cancel or suspend whenever you like.
Nine services in one tool
Countdowns, dynamic images and products, maps, surveys, polls, scratchers, slideshows and critical messages share one builder, one account and one impressions allowance.
Any email platform, no code
Each service is an image tag you paste into your ESP’s template, so there is nothing to install and no developer in the loop. It works anywhere that sends images.
Reachable from your own tools
On every paid plan, from Starter at $19 a month, a public REST API and an MCP server let you create and update services from your own code or from Claude, ChatGPT or Cursor, and a Zapier integration is in private beta.
Who uses Alterable
- In-house email and lifecycle marketers, mostly at e-commerce and DTC brands, who want a live countdown or current product data in a campaign without waiting on a developer.
- Email and design agencies running campaigns for several clients on different ESPs. Each client gets its own team, and teams are unlimited on every plan.
How Alterable works
- Sign up for the Free plan. No credit card and no sales call.
- Build a service in the browser builder.
- Paste its snippet into your campaign in your ESP.
- Every open draws the image for that reader, at that moment.
Setup is self-serve: the setup guides cover each ESP, and anything they don’t answer goes through the contact page. Starter adds email support, and Pro and Scale priority email support.
