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.

Tailwind CSS features and specs

  • Utility-First Approach
    Tailwind CSS uses a utility-first approach, promoting the use of small, reusable utility classes to style elements directly in your markup. This can lead to more readable and maintainable HTML.
  • Customization
    The framework is highly customizable. You can easily configure its default theme, add your extensions, and create custom utilities. Tailwind’s config file allows for deep customization of all aspects of the framework.
  • Consistent Design
    Using utility classes ensures design consistency because the same classes will apply the same styles globally.
  • Responsive Design
    Tailwind CSS has excellent built-in support for responsive design. You can easily apply different styles for different screen sizes using responsive utility variants.
  • Performance
    Tailwind purges unused CSS in production, resulting in smaller final output files and improved performance.
  • Integrates Well with Frameworks
    Tailwind CSS integrates smoothly with modern JavaScript frameworks like React, Vue, and Angular.
  • JIT Compiler
    The Just-in-Time (JIT) mode in Tailwind CSS generates styles on-demand, reducing the development build sizes and speeding up the development process.

Possible disadvantages of Tailwind CSS

  • Steep Learning Curve
    For developers coming from traditional CSS or other CSS frameworks, getting used to Tailwind's utility-first approach may take some time.
  • HTML Congestion
    Due to the utility-first approach, HTML files can get filled with numerous utility classes, making it look cluttered and harder to read.
  • Initial Setup
    Setting up Tailwind CSS initially can be complex, especially for beginners. Configuration settings and integrations with build tools can be confusing.
  • Verbosity
    Some developers find the inline utility classes verbose, particularly when complex styles are required, which can lead to bloated template files.
  • Limited Abstractions
    Tailwind doesn't provide higher-level abstractions such as components out of the box, like other frameworks (e.g., Bootstrap) do. Developers need to build and maintain these abstractions themselves.
  • Dependency Tailoring
    While Tailwind aims to be minimalistic, it may enforce some dependencies or build tool integrations that could be unnecessary for very simple projects.

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 Tailwind CSS 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.
