How Long Should You Wait Before Sending From a New Domain

Patience with new domains pays dividends in deliverability. Here is the timeline for getting a new domain ready for cold email. Week 1: Registration and setup Register the domain. Configure email hosting (Google Workspace or Microsoft 365). Set up SPF, DKIM, and DMARC. Build a simple landing page. Create email accounts. This can be done in a day, but letting the domain exist for a week before starting warmup allows DNS records to fully propagate and establishes minimum domain age. Week 2–3: Warmup Start warmup on all accounts. The warmup tool sends and receives emails, building engagement history and sender reputation. Run warmup at increasing volume — start at 5 to 10 warmup emails per day and scale to 30 to 40 per day. Week 3–4: Deliverability testing After two weeks of warmup, test inbox placement using the deliverability checker. If your test emails land in the primary inbox across Gmail and Outlook, you are ready to start sending campaigns. If not, continue warmup for another week and test again. Week 4+: Campaign launch Begin sending cold emails at low volume — 5 to 10 per account per day. Ramp up by 5 every few days until you reach your target volume (25 to 35 per day per account). Total time: 3–4 weeks from registration to full campaign volume. This is why many teams plan their infrastructure weeks or months in advance of their campaign calendar. If you need to send sooner, prewarmed inboxes from Warm Inboxes cut this timeline dramatically because the warmup has already been completed.
