Cold email deliverability checker

Cold email checklist

• Use a secondary domain for outreach (e.g. getyourbrand.com). Never cold email from your brand domain.
• Warm up for 2-4 weeks before real campaigns. Start at 20-30 sends per day per mailbox and ramp slowly. Use the warm-up calculator to get a day-by-day schedule.
• Keep volume low: under 50 cold emails per mailbox per day once warmed up.
• One recipient per email, a real reply-to address, and plain text. No images, no heavy HTML.
• Align SPF, DKIM and DMARC with the provider you actually send through, the check above verifies that.
