Why not just use your work email?

1. Each inbox can only send a little. Email providers watch for accounts that suddenly send hundreds of emails to strangers. A safe cold inbox sends a few dozen emails a day. To reach thousands of people a month you need many inboxes.
2. Your main domain is too valuable to risk. If cold emails from yourcompany.com get marked as spam, your normal business email — invoices, replies to clients — starts landing in spam too. Cold email goes out from separate, similar-looking domains (like getyourcompany.com) so your main domain is never exposed.
3. New inboxes need warming up. A brand-new inbox that starts sending cold email looks suspicious. Warm-up is a few weeks of gentle, automatic sending that builds its reputation first.
4. The technical records must be right. SPF, DKIM and DMARC are DNS records that prove your emails really come from you. Get them wrong and providers send you to spam.

What Maildeck does

Maildeck buys and sets up the domains, creates the inboxes on Google Workspace, Outlook or SMTP, configures SPF/DKIM/DMARC, warms them up, and connects them to your sequencer.
