INBOX

INBOX is an email marketing platform aimed at small teams who actually run campaigns to specific lists, not the four-billion-email Mailchimp giants. You get a drag-and-drop builder, behavior-based automation, A/B split testing, and real-time dashboards, all under one login, paid once instead of monthly. The pitch is straightforward: keep the features, lose the recurring bill.

What INBOX actually does

The bones of any email platform are list management, sending, and reporting. INBOX bundles those with a multi-brand wrapper so several lists can live behind one account, plus the marketing-tech checklist you'd expect from a tool charging $40 a month on a subscription.

• Store up to 10,000 contacts and send unlimited campaigns to them
• Run up to 10 brands from a single login, handy for agencies or creators juggling several projects
• Build unlimited groups, segments, and web forms to capture and slice your list
• Run A/B split tests on subject lines, send times, and content variants
• Auto-resend each campaign to subscribers who didn't open it the first time
• Trigger marketing automations based on opens, clicks, dates, and list actions
• Drop in ready-made templates or build your own with the drag-and-drop editor
• Watch open rates, click rates, and segment performance in real-time reports
• Connect to Zapier, JotForm, TypeForm, WooCommerce, and Shopify out of the box

Who it's built for

INBOX is at its best when you're running more than one list. A small agency with three client newsletters, a creator with two side projects under separate brands, an e-commerce operator with a main store and a spin-off — that's the sweet spot. The 10,000-contact ceiling rules out big publishers, but most growing lists won't see that wall for a while.

If you're paying Klaviyo or ActiveCampaign $40 to $80 a month and using maybe a fifth of what they offer, the swap math is easy. The honest caveat: smaller ESPs rarely have the deliverability reputation of the giants, so warm up your sending domain on a small segment before pushing the whole list through. The platform also caps at 10,000 contacts, so anyone past that needs a different tool entirely. For everyone in the middle bracket, paying too much and using too little, this is the kind of swap that pays for itself in a quarter and then keeps paying every month after that.

The deal

The entry tier is one code at $99, down from $302, which unlocks the full platform with 10,000 contacts and unlimited sends. Two codes ($198) and three codes ($297) are also on the table if you want more headroom or plan to run several client accounts.
