Frankly, a 14% spam rate during warmup is a red flag, not a green light. Outlook showing 0% inbox is especially concerning - it's usually the strictest filter, so if you're failing there, your infrastructure still needs work. i wouldn't launch a full campaign yet.
The 60 emails that hit inbox during warmup are deceptive. Those warmup services (like Instantly) use honeypot networks that don't reflect real-world sender reputation. real recipients treat your mail differently. I've seen clients get lulled into a false sense of security before their domain gets burned within a week.
Before you send, check a few things:
Make sure your DMARC is set to p=quarantine or p=reject. Most people skip this and wonder why Gmail starts blocking them after week two. I'd run a quick check with a tool like dig _dmarc.yourdomain.com TXT to verify.
Keep your sending domain completely separate from your main business domain. If your primary domain gets flagged for cold email, transactional emails break too. Learnt that the hard way when a client's order confirmations stopped working because their main domain ended up on a blocklist.
Warm for at least two more weeks, but with real conversational replies - not just automated tools. Subscribe to industry newsletters you actually read and reply with genuine questions. Get people to respond to you. Reply rate is the strongest deliverability signal Microsoft and Google look at.
What's your target volume per day? That changes a lot about how you should structure your sending infrastructure.
