Premium Inboxes.

Our take, from the directory

Google and Microsoft inboxes built specifically for cold email scale, provisioned fast and priced for volume. We partner with them, and we'd recommend them anyway.

Premium Inboxes is sending infrastructure: the inboxes and mailbox plumbing under a campaign. It earned its place in the GrowthPal tool directory, where every entry is written from the operator's side of the desk: clearly marked partnerships and one practical take per tool.

Where it fits: underneath everything. Sending infrastructure is disposable by design, so your primary domain never touches a cold send.
