In practice
What it means for you.
Our reading of the facts above. Not a promise, and not the only reasonable reading.
Warmy sits beside your sender
If you already send from another tool, Warmy fits next to it. Warmerly can do that too, with campaigns switched off.
One tool or two
If you want to warm and send from the same mailboxes, Warmerly does both. With Warmy you keep a separate sender.
Most people pair a warmer with a sender
If you already send from Instantly or Smartlead, either tool can warm the mailbox. Warmerly adds a sender if you want one tool.
Keep one tool in charge of warmup
If you send from another tool, leave Warmerly's campaigns off so it only warms.
