What is Inframail?
Inframail provides cold email infrastructure with a flat-fee pricing model for unlimited inboxes. Unlike per-inbox providers, you pay one price and create as many inboxes as you need.
They use Microsoft infrastructure, which generally offers better deliverability than pure budget shared-IP providers.
Key Features
Unlimited Inboxes Flat monthly fee regardless of inbox count. Create 10 or 100, same price.
Dedicated US IPs 1 IP on Unlimited plan, 3 IPs on Agency Pack. Your own sending reputation.
Free Domains Included 10 domains on Unlimited, 20 on Agency Pack.
Automated Setup DNS records configured automatically. Unlimited domain setups per day.
API Access Programmatic management included on both plans.
Pricing
Inframail has two flat-fee plans with unlimited inboxes:
Unlimited Plan - $129/month:
- 80,000 cold emails/month capacity
- 1 dedicated US IP
- 10 free domains
- Unlimited email inboxes
Agency Pack - $327/month:
- 300,000 cold emails/month capacity
- 3 dedicated US IPs
- 20 free domains
- Unlimited email inboxes
Both include API access, deliverability consultant, and priority support. The per-inbox cost drops to nearly nothing at scale.
Deliverability
Dedicated US IPs give Inframail an edge over shared-IP budget providers. You're not sharing reputation with random users on the same IP pool.
The Agency Pack's 3 IPs provides more sending capacity and redundancy than the single IP on the Unlimited plan.
For teams at scale, it's a solid middle ground between budget and premium.
Who Should Use Inframail?
Good fit:
- Teams needing 50+ inboxes
- Agencies managing multiple client campaigns
- Anyone who wants predictable costs at scale
- Teams who've outgrown pure budget providers
Not ideal for:
- Small teams with <20 inboxes (per-inbox pricing is cheaper)
- Teams needing premium isolated infrastructure
- Very low volume senders
Pros & Cons
Pros
- Unlimited inboxes for flat fee, great for scale
- Microsoft infrastructure better than shared IPs
- Quick setup with auto DNS configuration
- Predictable costs regardless of volume
Cons
- Less premium than Google Workspace
- Limited customization options
- Newer provider, less track record
Our Verdict
Inframail's unlimited model is compelling for teams at scale. The Microsoft infrastructure provides better deliverability than budget alternatives, and the flat fee makes costs predictable.
Best for teams needing 50+ inboxes. If you're smaller, per-inbox pricing from budget providers may be cheaper.
