Use a separate sending domain
The first rule of cold email is to keep it away from the domain you run your business on. Register a separate domain for outreach, so that if its reputation takes a hit, your primary email is untouched.
This is groundwork you own. Sellora AI runs outreach through mailboxes you connect, which means the domains and their reputation are yours to set up and protect.
Authenticate everything
Three records decide whether a receiving server trusts your mail. SPF says which servers may send for your domain. DKIM signs the message so it cannot be tampered with. DMARC tells receivers what to do when a message fails the first two.
Set all three before you send anything. Missing authentication is one of the fastest routes to the spam folder, and it is entirely avoidable.
Warm up and ramp slowly
A brand new mailbox that sends a hundred cold emails on day one looks exactly like a spammer. Warmup is the process of building a sending reputation gradually, starting with low volume and increasing it over weeks.
Patience here is not optional. The reputation you build slowly is the thing protecting every campaign you run afterwards.
Monitor placement, not just sends
A sent email is not a delivered one, and a delivered one is not necessarily in the inbox. Watch your bounce rate, your spam complaints, and where you can, actual inbox placement rather than assuming the best.
When the numbers slip, slow down and find the cause before you scale back up. Deliverability is maintained, not solved once.
Sellora AI is a fully autonomous Virtual SDR built to handle everything before the sales meeting, from prospect discovery and research to personalised outreach, live AI calls, follow-up, qualification and meeting booking. It runs that outreach through the deliverability groundwork you own.
The deliverability layer described here, the domains, warmup and monitoring, sits on your side. Sellora AI sends through the mailboxes you connect rather than providing this infrastructure for you.
