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.
Atmail AlterableAtmail is particularly suited for small to medium-sized businesses and individuals who prioritize simplicity and reliability over extensive features. It's ideal for users who are looking for a straightforward, easy-to-navigate email client that can handle standard email tasks effectively.
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.
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.
