Why Gmail mailboxes need warming
A brand-new Google Workspace inbox has no sending history. Google watches volume spikes, bounce rates, and spam complaints closely — especially when a fresh account starts sending a lot of email right away.
The result is predictable: messages land in spam, replies dry up, and a domain you just set up is already in trouble. Warming fixes that by establishing normal sending patterns first.
SuperWarm exchanges natural-looking emails with a warming network so Google sees opens, replies, and consistent inbox placement — the signals that matter before you send more.
What you get
OAuth connect
Sign in with Google. No app passwords, no fragile SMTP configs. Setup takes minutes per mailbox.
Fully automatic
Warming runs daily without spreadsheets or manual reply chains. Connect and let it work.
Gradual volume ramp
Activity increases over time so Google sees human-like patterns, not a sudden blast from a cold inbox.
Works with any email tool
SuperWarm only warms the mailbox. When you are ready, send from the same inbox however you like.
How Gmail warming works with SuperWarm
- 1
Connect your Workspace mailbox
Authorize SuperWarm via Google OAuth. We only need permission to send and receive warming emails.
- 2
Warming runs in the background
Short, conversational emails move through our warming network. Opens and replies build positive reputation signals.

Send more when ready
After 2–4 weeks of consistent warming, use the inbox normally and increase volume with more confidence.
What to expect
Most people warm a new Gmail mailbox for 2–4 weeks before sending at higher volume. Older domains may need less time; aggressive volume targets may need more.

Gmail warming FAQ
- Does SuperWarm work with Google Workspace?
- Yes. SuperWarm connects to Google Workspace mailboxes via OAuth — the same secure flow you use for other business apps. We recommend workspace inboxes for work email; personal @gmail.com accounts may work too.
- Can I warm a mailbox before using it for regular email?
- Yes — that is the point. Warm first with SuperWarm, then send from the same inbox with whatever email tool you use once reputation is established.
- How many Gmail mailboxes can I warm?
- Free supports up to 10 mailboxes. Pro is $49/month for unlimited mailboxes — one flat price, no per-inbox math.
- Will warming emails look like spam to Google?
- No. Warming messages are short, conversational, and exchanged within a controlled network designed to generate positive engagement signals like opens, replies, and inbox placement.
