Questions & Answers

As answered by people managing Alterable and Postalion.

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.

Postalion's answer:

It is a complete newsletter tool that runs inside your own WordPress, with no outside account and no limit on subscribers or emails in the free plugin. Your list stays in your database, statistics are counted on your server, and nothing is sent to outside services unless you choose a sending service yourself.

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.

Postalion's answer:

Hosted services like Mailchimp charge more as the list grows and keep your subscribers on their servers. Other WordPress plugins often cap subscribers or sends in their free version. Postalion has no such limits, imports your list from Mailchimp, MailPoet or the Newsletter plugin in a few clicks, and works with the plugins you already run: WooCommerce, course and membership plugins, donation and form plugins.

How would you describe the primary audience of your product?

Postalion's answer:

WordPress site owners who want to send newsletters without a monthly bill: bloggers, small shops, course creators, membership sites, nonprofits, local businesses and agencies that build sites for them.

What's the story behind your product?

Postalion's answer:

It started as a plugin for a single site and grew into a full newsletter tool. It is made by Alex Gurghis at FantasyThemes and was released on WordPress.org in October 2026. The free plugin stays complete; an optional add-on, Postalion Pro, funds its development.

Which are the primary technologies used for building your product?

Postalion's answer:

PHP and the WordPress APIs, with its own database tables for subscribers, lists and the email log. Sending runs in the background in batches through WP-Cron, via the site's mail function or any SMTP service. The sign-up form is a native block for the block editor, with elements for Elementor, Beaver Builder, Bricks and Divi.
