Cold Email Infrastructure You Need to Land in Primary

Global Customer Domain Tracking (GCDT)

Links in cold emails — without killing deliverability. The old rule “never include links in cold emails” no longer applies.

Maildoso’s Global Custom Domain Tracking lets you safely include links, images, and media — even in your first cold email — without triggering spam filters.

You can now confidently include:

• Loom product demos
• Calendly booking links
• Case study videos
• Interactive testimonials
• Website screenshots

IP rotation

Maildoso automatically rotates sending IPs to prevent reputation buildup on any single IP and to avoid pattern-based filtering.

• Prevents sudden inbox placement drops.
• Reduces the risk of IP-level blacklisting.
• Keeps large-scale outbound consistent and stable.

Self-healing mailboxes

Mailboxes that recover automatically — no manual babysitting

When you manage dozens or hundreds of mailboxes, some will inevitably lose performance. Maildoso detects underperforming mailboxes and heals them automatically — no manual tracking or replacement required.

How it works:

• Mailboxes are paused automatically when performance drops
• After a short rest period, they’re reactivated
• Even healthy mailboxes get brief breaks to prevent burnout

Built-In Reputation Measurement

Know the health of every mailbox — before deliverability drops

Every three days, Maildoso runs deliverability checks on each mailbox so you always know where you stand. From your dashboard, you can instantly see:

• Health scores for Google & SMTP mailboxes
• Active vs. burned status
• Date of the latest reputation check
