Custom Tracking Domain for Cold Email: What It Is and How to Set One Up
Why open, click and unsubscribe links should use your own subdomain instead of a shared one, and how to set up a custom tracking domain with one CNAME record.
Product comparison
MailQV focuses on simple cold-email operations and unlimited mailbox connections on paid plans. Instantly offers teams that want a broad outbound suite and a large established ecosystem.
No invented deliverability promises. You control the mailboxes and sending limits.

Both products support structured outbound workflows, but they are designed around different levels of breadth.

Built for teams that want a broad outbound suite and a large established ecosystem.
MailQV prioritizes a focused sending workflow, while the platform scope differs by product.
02
MailQV paid plans include unlimited connected mailboxes and meter monthly email sends and active contacts. Instantly uses plans and allowances that should be confirmed on Instantly’s official pricing page. Because competitor pricing changes, verify its current official page before buying.
03
MailQV lets a campaign use selected eligible mailboxes, while each mailbox retains its own daily controls and Safe Mode settings. Compare the exact sender limits and rotation rules you need in both products.
04
MailQV supports timed follow-up steps, sending schedules and reply-aware stopping. Confirm any specialized branching or multichannel automation directly in each product.
05
MailQV provides lists, tags, custom fields, suppression states, Gmail, Microsoft and SMTP/IMAP connections, plus campaign and mailbox analytics. Provider availability can depend on production approval.
06
Instantly includes a broader platform footprint, including adjacent lead and workflow capabilities. Review those capabilities alongside your existing outreach process.
07
MailQV is deliberately simpler and does not price paid plans by connected-mailbox count. It keeps plan allowance, mailbox capacity and campaign controls conceptually separate.
