Comparison
Warmerly vs Warmy.io
Warmy.io is an email deliverability platform built around a large warmup network, an AI assistant called Adeline, and a US seed list for placement testing. It is aimed at higher-volume senders and no longer publishes prices — every plan is volume-based and quoted after a demo or trial. Warmerly publishes its prices on the pricing page: $19/month for 5 mailboxes, $49 for 25.
Our verdict
Warmy.io is the more heavily resourced product, and for a high-volume B2C sender who wants a large seed list, an AI co-pilot and a named contact to call, that resourcing is worth paying for. The trade is that you cannot find out what you will pay without asking, and volume-based pricing on a warmup tool means your bill moves with your sending. Warmerly is the smaller, plainer option: a published flat price, no sales call, and every mailbox on your plan warmed at full volume. If you are running 5 to 25 mailboxes and want to know the cost before you commit, that is the whole argument. If you are sending at a scale where a dedicated deliverability expert pays for itself, Warmy is the better fit and this page is not going to pretend otherwise.
