ColdSend pricing is built on one idea: every plan is made of the same unit. Understand that unit and the whole pricing page makes sense.
Here is how it works.
The Atom: One Infra Bundle
The building block of every ColdSend plan is one Infra Bundle. It is the same atom whether you are on Growth, Scale, or Agency.
One Infra Bundle gives you:
- 4 domains
- 100 inboxes per domain (400 inboxes total)
- 100,000 emails/month of sending capacity
- Pre-warmed IPs — the inboxes send from Azure enterprise IPs with established reputations from day one
That is the atom. 4 domains. 400 inboxes. 100K sends. Pre-warmed IPs.
Every plan is just a question of how many of these atoms you get, plus which platform features are unlocked on top.
The Three Tiers
Growth and Scale both give you 1 Infra Bundle — the same 4 domains, 400 inboxes, 100K sends. The difference is platform features. Growth is the sequencer + the atom. Scale adds the developer and team layer (API, AI tools, warmup, team seats) on top of the same atom.
Agency gives you 2 Infra Bundles — 8 domains, 800 inboxes, 200K sends — plus all features, 10 team seats, and the ability to buy more atoms (add-on slots) at $49/mo each (BYOA) or $99/mo each (DFY).
Want more than 200K sends? Add another atom to Agency. Each one is +4 domains, +400 inboxes, +100K emails. Simple as.
BYOA vs DFY: Who Runs the Azure Account
Every Infra Bundle runs on Azure Communication Services — Microsoft's enterprise email infrastructure. The only decision beyond picking a tier is who owns and manages the Azure account that powers your atoms.
BYOA (Bring Your Own Azure):
- You create the Azure account. You pay Microsoft directly (~$2/month).
- You own the tenant, the IPs, and every inbox created there.
- ColdSend automates the setup (DNS, inbox creation, monitoring) on top of your account.
- Takes about 5 minutes. Follow our setup guide.
- The cheaper option. Full infrastructure ownership.
DFY (Done For You):
- We create and manage the Azure account for you.
- No Azure portal. No Microsoft bill. No setup steps.
- It is bundled into your plan price.
- You still own the inboxes and can export them anytime — but the Azure tenant is managed by us.
- Costs $20–$100 more per month depending on the tier.
Why both exist: Some users want total control and ownership (BYOA). Others just want to send emails and never think about Azure (DFY). The toggle lets you switch between them anytime without changing tiers.
If you already have an Azure account for other services, BYOA is the obvious choice — reuse it and pay ~$2/month. If the words "Azure portal" make you nervous, pick DFY and let us handle it.
What Each Plan Includes
Growth ($79/mo BYOA or $99/mo DFY)
- 1 Infra Bundle (4 domains, 400 inboxes, 100K sends, pre-warmed IPs).
- Unlimited leads.
- Full sequencer (campaigns, variants, analytics).
- Unlimited imported inboxes (Gmail, Outlook, SMTP) on top of your Infra Bundle.
Growth is the entry point. One atom, the full sequencer, nothing else. No API, no warmup tool, no team seats. For solo senders, this is usually enough.
Scale ($129/mo BYOA or $179/mo DFY)
- 1 Infra Bundle (same 4 domains, 400 inboxes, 100K sends).
- Unlimited leads.
- Full sequencer.
- Full API + AI tools (MCP, Claude Code integration).
- Warmup and reputation monitoring.
- 4 team seats.
Scale is Growth plus the features teams need: API access for automation, warmup for reputation management, and team collaboration. Same atom, more platform on top.
Agency ($199/mo BYOA or $299/mo DFY)
- 2 Infra Bundles (8 domains, 800 inboxes, 200K sends).
- Unlimited leads.
- Full sequencer.
- Full API + AI tools.
- Warmup and reputation monitoring.
- 10 team seats.
- Add-on Infra Bundles: $49/mo each (BYOA) or $99/mo each (DFY). Each one adds 4 domains, 400 inboxes, and 100K sends.
Agency is for agencies managing multiple clients. Two atoms out of the gate. When you need more, add atoms at $49/mo each (BYOA) — no need to change plans. Each atom is the same 4 domains, 400 inboxes, 100K sends.
What Costs Extra
There are no setup fees. No per-client workspace fees. No hidden sequencer costs. The price you see is the price you pay.
The Real Cost at Different Volumes
Because every atom is the same 4 domains / 400 inboxes / 100K sends, the cost math is simple. Here is what you actually pay at different send volumes (using BYOA prices):
Each additional 100K emails = one more Infra Bundle = $49/mo (BYOA). The math is linear. There is no "tier cliff" where the price jumps unpredictably.
Compare this to providers that charge per inbox or per client workspace. At 15 clients, some competitors cost $600+/month. ColdSend Agency is $199 flat (BYOA) — no per-client fees, ever.
Common Pricing Questions
"What is an Infra Bundle?"
It is the atom of every ColdSend plan. One Infra Bundle = 4 domains, 100 inboxes per domain (400 total), 100K emails/month, pre-warmed IPs. Growth and Scale each include 1. Agency includes 2 and lets you add more at $49/mo (BYOA) or $99/mo (DFY) each.
"What is BYOA and what is DFY?"
BYOA = Bring Your Own Azure. You create the Azure account, pay Microsoft ~$2/month, and own everything. DFY = Done For You. We create and manage the Azure account for you, included in your plan price. You can switch between them anytime.
"Do I need an Azure account?"
Only if you choose BYOA. With DFY, we handle it — you never touch the Azure portal. With BYOA, you create one Azure account (~$2/month from Microsoft) and ColdSend automates everything on top. It takes about 5 minutes.
"What is a slot?"
A slot is a platform permission to attach one Infra Bundle. Each slot = 4 domains, 400 inboxes, 100K sends. Growth and Scale each include 1 slot. Agency includes 2 slots and lets you add more at $49/mo (BYOA) or $99/mo (DFY).
"Can I import my own Gmail or Outlook inboxes?"
Yes, on any plan. Imported inboxes are separate from Infra Bundle slots — you can mix pre-warmed Azure IP inboxes with your existing Google/Outlook/SMTP inboxes on any tier. Imported inboxes do not count against your Infra Bundle send limit.
"What happens if I exceed my email limit?"
Growth and Scale include 100K emails/month (1 Infra Bundle). Agency includes 200K (2 Infra Bundles). If you need more, add Infra Bundles to Agency ($49/mo BYOA each — each adds 100K). You can also rotate volume to imported inboxes, which do not count against your Infra Bundle limit.
"Are there any setup fees?"
No. You pay the monthly plan price. Azure costs ~$2/month if you choose BYOA. That is it. No upfront costs, no initiation fees, no per-client charges.
"Can I upgrade or downgrade later?"
Yes. Start on Growth, upgrade to Scale when you need API or team seats, or jump to Agency when you need a second Infra Bundle and higher volume. Switch between BYOA and DFY anytime.
Bottom Line
ColdSend pricing is one atom, three tiers, and one toggle.
The atom: 4 domains, 400 inboxes, 100K sends, pre-warmed IPs. Every plan is built from this.
The tiers: Growth (1 atom, $79 BYOA), Scale (1 atom + API/team features, $129 BYOA), Agency (2 atoms + all features + add-ons, $199 BYOA). Each tier is the same atom with more platform on top.
The toggle: BYOA (you run the Azure account, ~$2/mo) or DFY (we run it, bundled in your plan). Switch anytime.
If you want the simplest possible start: Growth ($79/mo BYOA), 1 atom, 100K sends, pre-warmed IPs. If you need API and team features: Scale ($129/mo BYOA). If you are an agency managing multiple clients: Agency ($199/mo BYOA) with add-on atoms as you grow.
