The agency email problem
Agencies inherit whatever their clients bring: lists of unknown provenance, domains with unknown histories, and campaign calendars driven by client urgency rather than deliverability sense. One client arrives with a purchased list. Another insists on blasting a two-year-old database before a product launch. If all of that runs through anything shared, the client with clean practices pays for the client without them.
And when placement drops, it's the agency that has to explain it. "Deliverability is complicated" doesn't survive a quarterly business review. What survives is a mechanism: this happened, here's the data, here's the fix, here's how we've isolated it.
Isolation is the architecture
The structural answer is per-client separation. Each client sends from their own domains, and the platform tracks and paces reputation per domain in real time. When one client's send starts generating bounces or complaints, the reputation engine slows that client's domains before mailbox providers punish them, and nobody else's sending is touched. The blast radius of any mistake is one client, contained.
Within each client, transactional and campaign streams stay on separate reputations too, so a promo misfire doesn't take down the client's receipts and password resets. Isolation applies twice: between clients, and within them.
Deliverability as a service you can resell
For an agency, deliverability competence is billable. Onboarding a client's domain properly, auth set up and aligned, warmup before volume, list checked before the first send, is a service line, not overhead. The free deliverability check makes a decent pitch tool: run it on a prospect's domain in the meeting and walk through what it finds.
Where it fits
- Campaign sending across a client roster — each brand on its own domains, individually paced.
- Client onboarding — auth setup, alignment verification, and warmup as a repeatable process.
- Reporting — per-domain reputation and engagement data you can put directly in client decks.
- Damage containment — when a client insists on a risky send, the engine limits how much harm it can do, to them and only them.

Common questions
Why is email different for an agency than for a single brand?
Because you're carrying other people's reputations. A brand that ruins its own deliverability hurts itself; an agency that lets one client's bad list drag down a shared setup hurts every client on it. The structural answer is isolation: each client sends from their own domains with their own reputation, so one client's mistake never becomes another client's spam folder.
Can one client’s bad campaign affect my other clients here?
Not if the domains are separated, and they should be. Reputation on this platform is tracked and paced per domain. If client A's list turns out to be stale and complaint-heavy, the reputation engine throttles client A's domains while everyone else keeps sending at full speed. That per-domain isolation is the core of running agency email safely.
How do I explain deliverability problems to a client?
With data instead of hand-waving. The dashboard shows per-domain reputation, bounces, complaints, and pacing decisions, so 'your open rates dropped because your last list import generated complaints and sending was slowed to protect the domain' is a sentence you can back with numbers. Clients accept bad news that comes with a mechanism far better than vague reassurance.
Do you support Indian agencies on billing?
Yes, INR pricing through Razorpay with GST-compliant invoices. If you're an Indian agency reselling email as part of retainers, your accounting works normally, no USD card reconciliation and no lost input credit.
What should an agency check before onboarding a client’s list?
Three things, before the first send. Where the list came from, purchased and scraped lists are how you inherit spam traps. Whether the client's SPF, DKIM, and DMARC are set up and aligned, run the free deliverability check on their domain. And how old the engagement is, addresses that haven't been mailed in a year need a re-permission pass, not a full blast. Ten minutes of checking beats a month of reputation recovery.
