Email warm-up that builds reputation before you scale
A brand-new mailbox has no sending history. Sending hundreds of emails on day one is exactly what spam filters look for. AGS Orbit ramps every mailbox up gradually and keeps a light warm-up running.
Why warm-up matters
Mail providers judge a sender by its history: how much it sends, how often mail bounces, and whether people open and reply. A new mailbox that suddenly sends at full volume looks like a spammer. Warm-up builds a positive history first, so your real campaigns are trusted.
How AGS Orbit warms up a mailbox
- Daily caps that rise slowly — from about 5 emails a day up to 400 over roughly four weeks.
- Warm-up emails between your own mailboxes on different domains, written like normal work emails.
- Engagement signals: warm-up mail is opened, moved out of Junk when needed, and some messages get replies.
- Inbox-rate tracking per mailbox, so you can see how each one is doing.
Warm-up keeps running
After the ramp, each mailbox keeps a light 2–3 warm-up emails a day alongside your campaigns. Warm-up emails are not counted against your campaign volume and are kept out of Sent Items where the provider allows.
Pair warm-up with the basics
Warm-up works best with SPF, DKIM and DMARC set up correctly. AGS Orbit checks all three for every sending domain and shows the exact DNS record to add if something is missing.
Frequently asked questions
How long does email warm-up take?
Campaign sending is capped low for the first days and grows to full volume over about four weeks. You can send real campaigns during warm-up — the cap simply keeps volume safe.
Does warm-up work for Microsoft 365 and Google Workspace?
Yes, and also for Zoho, Rackspace and other SMTP/IMAP mailboxes.
Can I turn warm-up off?
Yes, per mailbox. We recommend keeping it on for any mailbox younger than a month.
