Alterable adds real-time, open-time content to email campaigns, no coding, no ESP integration, no resends. Every asset is a single image URL that renders fresh the moment a subscriber opens the message, not the moment you hit send.

Countdown timers count down live in the inbox. Choose a fixed deadline for your whole list, an evergreen timer that starts when each subscriber opens, or a per-recipient deadline pulled from a merge tag. Ten visual styles, full color and font control.

Dynamic images show a different visual to every recipient based on location, device, language, weather, temperature, or time of day. A no-code rules builder stacks conditions and maps each combination to its own image variation.

Dynamic products pull live price, stock, and availability at the moment an email opens. Sold-out items hide automatically; low-stock items get a scarcity badge. Sync via CSV, REST API, or a Shopify/BigCommerce connection.

Local maps show each subscriber their nearest store, rendered around their location at open-time. Four map styles, custom markers, and deep links to native navigation apps.

Surveys put a one-click star, number, or emoji rating directly in the email body, no landing page, no login. Results populate a live dashboard as votes arrive.

Scratchers turn a discount into a game: a scratch-card reveal linking to a hosted prize page, with customizable cover art, reveal animations, and (on Pro) multiple weighted prizes.

Every asset works the same way: build it in Alterable's editor, copy one image tag, paste it into any ESP. Because it's just an image, it works in every major email client, no JavaScript or AMP required. Integrates with 50+ platforms including Klaviyo, Mailchimp, HubSpot, Brevo, ActiveCampaign, Constant Contact, GetResponse, AWeber, and Kit.

Also included: 22-language localization, timezone support, real-time analytics, CDN delivery, and REST API access. Free to start, no credit card required.

Glitch features and specs

  • Real-time collaboration
    Glitch allows multiple users to edit code simultaneously, similar to Google Docs, making it easier for teams to work together.
  • Instant deployment
    Projects on Glitch are deployed instantly upon saving, which allows developers to see the results of their changes immediately without additional configuration.
  • Beginner-friendly
    The platform is very accessible for new developers, offering a low barrier to entry with its simple interface and supportive community.
  • Remixing
    Glitch supports 'remixing,' which allows users to fork existing projects easily and build upon them, facilitating learning and quick experimentation.
  • Free tier
    Glitch offers a robust free tier that provides sufficient resources for many small projects, making it a cost-effective solution for early-stage development.

Possible disadvantages of Glitch

  • Performance limitations
    The free tier has resource limitations, such as sleep timers for inactive projects and restricted CPU and memory allocation, which may not be suitable for high-performance applications.
  • Limited backend languages
    While Glitch is great for web development, its support for backend languages is primarily focused on JavaScript (Node.js), limiting flexibility for projects needing other backend technologies.
  • Lack of advanced features
    For more experienced developers, Glitch might lack some advanced features like detailed performance monitoring, fine-grained access control, and custom domain support without additional cost.
  • Dependency management
    Handling a large number of dependencies can become cumbersome, and the platform may not support advanced dependency features available in other environments.
  • Project size limitations
    Glitch imposes limits on project storage, which can be restrictive for larger applications or those requiring significant assets and dependencies.

Alterable features and specs

  • Countdown Timers
    Live, ticking countdown images embedded in email via a single <img> tag. Re-rendered fresh every time an email is opened.
  • Dynamic Images
    Serves a different image per recipient based on location, device, language, weather, temperature, time of day, or custom rules, rendered at open-time.
  • Dynamic Products
    Product blocks showing live price, stock level, and availability at the moment of open; auto-hides sold-out items, auto-badges low stock.
  • Local Maps
    Geo-targeted map showing each recipient's nearest store or point of interest, rendered at open-time from a CSV-imported location list.
  • Surveys
    One-click star, number, or emoji rating widgets embedded directly in email; no landing page or login required to respond.
  • Scratchers
    Scratch-card-style gamified prize reveal; Alterable hosts the resulting prize page.

Questions & Answers

As answered by people managing Glitch and Alterable.

What makes your product unique?

Alterable's answer:

Most tools in this space (NiftyImages, Sendtric, MotionMail, CountdownMail) do one thing well, usually just countdown timers. Alterable is a single platform for six distinct open-time content types, timers, dynamic images, live product data, geo-targeted maps, surveys, and scratch-card rewards, all rendered the same way: one image tag, no ESP integration, no JavaScript.

That "just an image" approach is also what makes it universal: it works in every major email client without exception, since there's nothing for Outlook or Gmail to selectively support or block.

The rules engine is shared across all six content types too. The same conditions (location, weather, device, time of day, stock level) that pick a dynamic image can pick a product, a map location, or a timer variant, so teams build a targeting logic once and reuse it everywhere instead of learning a separate tool per feature.

Why should a person choose your product over its competitors?

Alterable's answer:

Against single-purpose timer tools (Sendtric, CountdownMail, MotionMail, CountingDownTo): those platforms do one thing, a countdown widget. Alterable includes countdown timers plus dynamic images, live product data, geo-targeted maps, surveys, and scratch cards, on one account, with one shared rules engine. If a team outgrows "just a timer," there's no second tool to adopt.

Against broader personalization platforms (NiftyImages, Movable Ink): Alterable is free to start with no credit card, and every asset is a plain image tag rather than requiring a native ESP integration or account connection. That keeps setup to minutes and means it works identically across Klaviyo, Mailchimp, HubSpot, GetResponse, or any of 50+ platforms, with no per-ESP configuration to maintain.

Because it's "just an image": there's no JavaScript, no AMP, no interactive-email fallback logic to write or test. It renders the same way in Outlook as it does in Gmail, which is where more elaborate interactive approaches usually break first.
