How It Improves Inbox Placement and Deliverability

Mailforge improves inbox placement by making sure your technical setup is done correctly from day one.

• Since SPF, DKIM, and DMARC are automatically configured following industry best practices, it reduces common setup mistakes that can push emails to spam.

• Because the infrastructure is built specifically for cold outreach, it is structured around sending sequences at scale instead of general email usage.

• If a mailbox or domain causes issues, you can replace it without rebuilding your entire setup. That means one problem does not force you to restart everything.

• Domains are portable. If you switch sending tools later, you can keep using the same domains and mailboxes instead of starting from scratch.

• You can also reuse domains across campaigns, which saves time and keeps your infrastructure consistent.

• In simple terms, it gives you a flexible and structured setup where issues can be isolated and replaced, instead of breaking your entire outreach system.

Limitations

• Mailforge runs on a shared IP distributed infrastructure, so you do not get dedicated or private IP control.
  
  
• You must purchase a minimum of 10 mailbox slots, which may not be ideal if you only need a few mailboxes.
  
  
• Domains are not included by default and need to be purchased separately.

Limitations
