Frostmailer

Frostmailer is a cold email infrastructure tool that lets you create Gmail or SMTP inboxes and lets you achieve up to 99% deliverability with up to 70% open rates. Everything is done hands-free.

The support is also lightning fast and you can just get started with Google Workspace accounts from a US IP address within 48 hours and with SMTP inboxes, you can start within 30 minutes.

Frostmailer is being used by 100+ cold email experts. Working with Frostmailer is really easy. You just sign up with Frostmailer, fill out an onboarding form that would take you about 10 minutes, and get fully set up within 48 hours with Google and 30 minutes with SMTP. That means you can just get started sending emails within 40 with Google mailboxes and within 48 minutes with SMTP.

Also note that Frostmailer provides pre-bound SMTP inboxes that cost about $5. You will also get full Google admin access with 24/7 support for DNS settings done for you and US IP Google Workspace accounts.

Frostmailer is built for SMTP and is built for agencies and sales teams who want a hand-off or hands-off infrastructure experience that works from day one without any technical headaches or drawn-out setup.

All plans include auto-configured SPF, DKIM, and DMARC, domain reputation monitoring, and direct import into your preferred sending software.

Their clients average 99% deliverability and 70% open rates, and partner agencies have collectively generated over 3,000,000 euros in revenue from cold outbound campaigns run on FrostMailer infrastructure.

If you are building a complete cold email stack, you can pair FrostMailer infrastructure with sending platforms like Instantly, Woodpecker, Buzz.ai, SmartReach, or SmartLead.

For teams evaluating infrastructure providers, comparing FrostMailer against Primeforge Maildoso, ZapMail, and Inboxkit can help you choose the right balance between cost, setup speed, and deliverability focus.
