Business accounts send friendly emails to Gmail warm-up accounts. Gmails mark as "not spam" and reply to ~50%. This trains Google that your business emails are trusted. Volume starts at 3/day per account, grows over time. No cold emails allowed.

You can now send 3-5 cold emails per account per day, mixed with warm-up. Validate deliverability with warm leads first.

Send up to 80 cold emails per business account per day. Warm-up continues automatically in background.
