The cold email platform built for outbound agencies
Run cold email for every client from one place. Unlimited mailboxes and unlimited sending on one credit balance, done-for-you domains and mailboxes per client, and automatic deliverability protection across every account. Add clients without adding a stack of per-client tools.
Why agencies outgrow their cold email stack
Running outbound for clients breaks the single-user tools most agencies start with.
You pay for the same stack, per client
A verifier, a warm-up tool, a sender, a placement tester, and monitoring, bought again for every account. Margins disappear into a pile of subscriptions that grows with every client you win.
One burned client domain becomes your problem
When a client's mailboxes start slipping into spam, most tools only alert you, if that. By the time you notice, the domain reputation is already damaged and the client is asking why replies dried up.
Every client lives in a different login
Juggling separate dashboards per client, per tool, means no single view of what is landing, what is warming, and what is at risk across the book of business you actually manage.
One platform to run every client's outbound
The full cold email pipeline, verify, warm, send, test placement, and monitor, across all your clients on one balance.
Unlimited mailboxes and sending
Add clients, domains, and mailboxes without paying per seat or per inbox. Unlimited automated sending on one credit balance from $39.
Done-for-you client infrastructure
SpamCipher provisions dedicated secondary domains and warmed mailboxes for each client, with SPF, DKIM, and DMARC set up, so you skip the manual build.
Automatic inbox rotation
Every campaign spreads across a client's warmed mailboxes at safe, throttled pacing, so volume scales without burning any single inbox.
Deliverability protection per client
An always-on guard watches placement, bounces, and complaints on every mailbox and throttles, pauses, or rotates it out before a client's domain gets burned.
Placement and monitoring across accounts
Real seed-based inbox-placement tests, DMARC, blacklist, and domain-health monitoring on every client domain, scheduled and alerting when something slips.
Sequences, an AI reply agent, and an API
Build multi-step sequences per client, let an AI reply agent work every reply, and wire SpamCipher into your own stack with a full REST API.
The typical agency stack, versus one platform
What most agencies pay for per client, and what SpamCipher folds into one balance.
| Per client, you usually need | Typical stack | SpamCipher |
|---|---|---|
| List verification | Separate verifier, per credit | Built in |
| Mailbox warm-up | Separate warm-up tool | Built in, seed network |
| Sending at volume | Separate sequencer / sender | Unlimited, inbox rotation |
| Inbox-placement testing | Separate placement tool | Built in, per domain |
| DMARC, blacklist, domain health | Separate monitoring tool | Built in, continuous |
| Done-for-you domains + mailboxes | Manual, or another vendor | Provisioned for you |
| Billing | Many subscriptions, times every client | One balance, from $39 |
Why agencies switch
Fewer tools, protected client domains, and margin that scales with your book, not your subscriptions.
1. Margin that scales with clients, not tools
Unlimited mailboxes and unlimited sending on one balance mean adding a client does not add five subscriptions. The pipeline you resell runs on one predictable cost.
2. Client domains protected automatically
Deliverability is wired back into sending. When a mailbox slips, SpamCipher acts, throttle, pause, rotate out, before the damage reaches a client's reputation, instead of leaving you to catch it manually.
3. One dashboard, every client
Verification, warm-up, sending, placement, and monitoring for every account in one place, so you can see what is landing and what is at risk across your whole book.
Agency questions
Is SpamCipher a good cold email tool for agencies?
Yes. It is built for agencies running cold email across many clients: unlimited mailboxes and sending on one balance, done-for-you provisioning per client, sequences and an AI reply agent, and deliverability monitoring on every client domain, from one dashboard and one bill.
Can I manage multiple clients in one account?
Yes. Run separate campaigns, domains, and mailboxes per client from a single workspace, instead of a different login for every account.
Do you provision domains and mailboxes for clients?
Yes. SpamCipher provisions dedicated secondary domains and warmed mailboxes for each client, with SPF, DKIM, and DMARC set up, so you skip the manual build.
How does pricing work for an agency?
One credit balance covers verification, sending, warm-up, placement testing, and monitoring across all clients, starting from $39. Unlimited mailboxes and sending mean you do not pay per seat or per inbox as you add clients.
Does it protect each client's domain automatically?
Yes. An always-on deliverability guard watches each mailbox and automatically throttles, pauses, or rotates it out before it burns a client's domain, then recovers it when the numbers improve.
Can I replace my agency cold email stack with SpamCipher?
For most agencies, yes. It folds the verifier, warm-up tool, sender, placement tester, and monitoring into one platform, so you can retire several per-client subscriptions and run the whole pipeline in one place.
