This comes up a lot with ecommerce and newsletter people. You set up a new domain, connect it to Klaviyo or Mailchimp, and then realize traditional warmup tools don’t work because there’s no mailbox login. In those cases the practical option is seed-list testing. You send a normal campaign to a mixed group of Gmail, Outlook and Yahoo addresses, see where the emails actually land, and get some engagement signal at the same time. It’s not as straightforward as regular mailbox warmup, but it’s one of the few methods that currently works for platforms without SMTP or IMAP access. Most tools like Instantly and Smartlead can’t do this, while a few others including E-Warmup and Warmy offer some form of seed-list support. Anyone found a better approach for this?   submitted by   /u/Silly_Captain2089 [link]   [comments]
