Email Warmup
Email Warmup, Included: land in the inbox, not spam
Email warmup is the process of gradually building a mailbox sender reputation so your messages land in the primary inbox instead of spam. With AvairAI, warmup is included at no extra cost. Standalone warmup services charge $15 to $50 per mailbox each month; AvairAI builds it into every plan. When you start, AvairAI provisions authenticated domains and mailboxes (SPF, DKIM, and DMARC) so Gmail and Outlook trust them from day one. Every mailbox then runs through warmup before your first cold email goes out. The ramp is gradual and recipe-based: over roughly 30 days, your mailboxes exchange messages with a verified warmup pool that opens, reads, and replies, simulating natural sending. After the initial ramp, a small maintenance volume of about 10 emails a day keeps reputation strong. Warmup is the single biggest deliverability lift in cold outreach, and you do not manage any of it.
What email warmup does for deliverability
Cold outreach fails most often at the inbox, not the pitch. New domains and mailboxes have no sending history, so Gmail and Outlook treat them with suspicion. Send too much too soon and your messages route straight to spam, where no one sees them. Warmup fixes this by building a track record before you send a single cold email.
It works by establishing a positive sender reputation: steady, real-looking inbox activity that signals to mailbox providers that your domain is trustworthy. Warmup is the single biggest deliverability lift in cold outreach. Skip it and even a strong campaign underperforms. Do it right and your emails reach real inboxes, where your reps can do the selling.
How AvairAI warms up every mailbox
AvairAI runs warmup as a gradual, recipe-based ramp with quality gates, not a switch you flip on day one. Over roughly 30 days, each mailbox exchanges emails with a verified warmup pool that opens, reads, and replies, simulating the natural back-and-forth of a real person sending mail. Volume increases step by step as reputation improves, so you build trust at a pace Gmail and Outlook reward.
After the initial ramp, warmup does not stop. A small maintenance volume of about 10 emails a day keeps your sender reputation strong while your campaigns run. You do not configure pools, schedules, or thresholds. Every mailbox is warmed before your first cold email goes out, and it stays protected afterward.
Infrastructure and warmup, included at no extra cost
Warmup is only as good as the infrastructure under it. AvairAI provisions authenticated domains and mailboxes for you, with SPF, DKIM, and DMARC configured so Gmail and Outlook trust them from day one. You can also bring your own domains if you prefer.
Mailbox capacity scales with your plan:
- Starter ($99 per month): 1 domain and 4 mailboxes.
- Professional ($299 per month): 3 domains and 12 mailboxes.
- Growth ($999 per month): 10 domains and 40 mailboxes.
Standalone warmup tools charge $15 to $50 per mailbox each month. With AvairAI, warmup is built into every plan, so a Growth account with 40 mailboxes does not add a separate warmup bill.
Warmup, included
Standalone warmup services charge $15 to $50 per mailbox every month. AvairAI includes warmup in every plan, so a Professional account with 12 mailboxes pays nothing extra to land in the inbox.
Frequently asked questions
Is email warmup included with AvairAI or is it an add-on?
Warmup is included in every AvairAI plan at no extra cost. Standalone warmup services charge $15 to $50 per mailbox each month, but AvairAI warms every mailbox it provisions as part of your subscription. There is no separate warmup bill and nothing to switch on.
How long does email warmup take?
The initial ramp runs for roughly 30 days. During that time each mailbox gradually exchanges emails with a verified warmup pool that opens, reads, and replies, building sender reputation step by step. AvairAI warms every mailbox before your first cold email goes out, so you do not send while a domain is still cold.
Does warmup stop once my campaign starts?
No. After the initial 30-day ramp, a small maintenance volume of about 10 emails a day continues in the background to protect your sender reputation while your campaigns run. This keeps your domains trusted by Gmail and Outlook over time, not just at launch.
Can I use my own domains, or only AvairAI mailboxes?
Both. AvairAI provisions authenticated domains and mailboxes for you, with SPF, DKIM, and DMARC set up so Gmail and Outlook trust them from day one. You can also bring your own domains. Either way, every mailbox runs through warmup before it sends a cold email.
