Who Mailscale is best for

Outbound teams and agencies building secondary sending infrastructure who want mailboxes and domains created quickly rather than configured by hand. Best when paired with a dedicated sending tool such as Instantly.

Key features

  • Mailbox and domain generation
  • Automated SPF, DKIM and DMARC records
  • Works alongside sending tools such as Instantly

Why it’s worth it

It speeds up building sending infrastructure for volume outbound. Like any bulk inbox tool, it works best for campaigns kept separate from your main domain.

Things to consider

  • Some reviewers report that domains have to be bought inside Mailscale and that domain prices after sign-up differed from those advertised.
  • New inboxes need a warm-up period before full-volume sending, unless you pay for pre-warmed options.
  • Pricing and plan details are not fully transparent on its website.

FAQ

Mailscale: common questions

What is Mailscale used for?

Mailscale is used to create cold email mailboxes and outreach domains with the DNS authentication done for you, so outbound teams can scale sending without touching their main domain.

Does Mailscale send the emails itself?

Its core job is infrastructure. Mailboxes are typically connected to a separate sequencing tool, which runs the campaigns.

Mailscale vs Mailforge?

Both generate bulk cold email inboxes and domains with automated DNS. The choice usually comes down to price per inbox, whether you can bring your own domains and which sending tool you use.
