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.

Frequently Asked Questions About FrostMailer

1. What is FrostMailer and who is it for?

FrostMailer is a cold email infrastructure provider built for agencies, sales teams, and businesses that want to scale cold outreach without dealing with technical setup. It provides Google Workspace accounts and SMTP inboxes with fully automated DNS configuration, warmup, and sequencer integration so you can focus on sending emails rather than managing infrastructure.

2. What is the difference between Google Workspace and SMTP inboxes on FrostMailer?

Google Workspace accounts are official US IP-based Gmail accounts best suited for teams that want maximum deliverability and the trust that comes with sending from a Google account. They take up to 48 hours to set up. SMTP inboxes are more affordable starting at $1 per inbox, can be created and warmed in under 30 minutes, and are better suited for teams that need to scale volume quickly or want more control over their infrastructure.

3. How long does it take to get set up with FrostMailer?

Google Workspace accounts are fully set up and imported into your sending software within 48 hours of completing the onboarding form. SMTP inboxes are ready in as little as 30 minutes. The onboarding form takes less than 10 minutes to complete and FrostMailer handles everything from that point forward.

4. Does FrostMailer handle DNS setup?

Yes. FrostMailer automatically configures SPF, DKIM, and DMARC for every inbox on every plan. You also get access to DNS management, email forwarding, and website redirect controls directly inside the FrostMailer platform without needing to log into your domain registrar separately.

5. What sending tools does FrostMailer work with?

FrostMailer is compatible with all major email sequencers and outreach platforms. Once your inboxes are set up, FrostMailer imports them directly into your preferred sending software so you can start campaigns immediately without any manual CSV uploads or configuration on your end.

6. What is the pricing for FrostMailer?

Google Workspace accounts are priced at $3.50 per account for under 250 accounts, $3.25 for 250 to 499 accounts, and $2.80 for 500 or more accounts. Standard SMTP inboxes start at $1 per inbox with a minimum order of 3 inboxes. Pre-warmed SMTP inboxes are launching soon at $5 per inbox. All plans include DNS setup, deliverability monitoring, and sequencer integration.

7. What are pre-warmed SMTP inboxes and when are they available?

Pre-warmed SMTP inboxes are a new FrostMailer product currently launching soon. These inboxes come pre-warmed for 3 or more weeks before you receive them, meaning they already have an established sending reputation and can be connected and used to send cold emails in under 5 minutes. They will be priced at $5 per inbox with a minimum order of 3 inboxes and will include all the same DNS, monitoring, and management features as the standard SMTP plan.
