Use case · Agencies
Dedicated email infrastructure for every client. One platform.
SendChief gives agencies a workspace for every client — with its own dedicated VPS, ready mailboxes, domains and sending reputation. Flat pricing, unlimited workspaces, no per-seat tax. Built for email marketing, lead-gen, growth, SEO and white-label teams.
Why shared infra fails agencies
Agencies need more than shared mailboxes
Every agency we talk to is fighting the same four problems — none of them can be fixed by switching to yet another per-seat ESP.
Client reputation pollution
On shared-IP platforms, one bad client tanks deliverability for every other client on the same pool. Agencies lose campaigns (and clients) overnight through no fault of their own.
Per-seat pricing eats the margin
Instantly, Smartlead, Klaviyo, Google Workspace — they all charge per seat. Add ten clients with ten mailboxes each and the tool bill vapourises the retainer before you've even shipped the work.
Tool sprawl per client
Every client ends up with their own registrar login, DNS host, mailbox vendor, warmup tool and sending platform. Handover and offboarding become archaeology projects.
No clean client isolation
Mixing clients in one tenant means one workspace misbehaves and the rest suffer. Proper isolation requires either heroic process or a platform that enforces it by design.
How SendChief is built for agencies
A workspace-native platform, not a single-tenant tool
Every primitive in SendChief is designed around running many clients on one account without cross-contamination.
Workspace per client
Every client lives in their own isolated workspace with its own servers, domains, mailboxes and billing context. Owner, Admin and Member roles keep teammates and clients on the right side of the wall.
Subscription sharing across workspaces
Share your SendChief subscription across every client workspace you run. Provision new infrastructure under any client without spinning up new billing accounts.
Resource transfer between workspaces
Move servers, domains and mailboxes from one workspace to another in a few clicks — essential when onboarding a client who brings their own infrastructure, or handing a workspace back at the end of an engagement.
Bulk domain purchase wizard
Buy dozens of warming domains across clients in one flow at registrar rates, with DNS, SPF, DKIM, DMARC and DANE records automatically published to the right workspace.
Token-based team invitations
Invite teammates and clients to a workspace with a one-click token link — no seat licenses, no per-user billing, no manual provisioning.
Flat pricing, unlimited workspaces
One SendChief subscription, unlimited client workspaces. Your margin is the gap between your retainer and a flat platform bill — not a per-seat meter.
Who it's for
Every kind of agency running email for clients
SendChief's workspace model maps cleanly onto five distinct agency archetypes.
Email marketing agencies
Full-service agencies managing DTC and e-commerce senders. Workspace-per-client isolation and per-domain DNS control mean one client's problems never touch another's deliverability.
Lead-gen & cold email agencies
B2B outbound shops running cold email for SMB clients. Bulk domain purchase, dedicated VPS, and ready mailboxes that export straight to Instantly, Smartlead, Snov.io and Reply.io.
Digital & growth agencies
Generalist agencies where email is one of many services. Managed mail server infrastructure without a sysadmin on staff — set up a client workspace, hand over the mailboxes, move on.
White-label resellers
Small shops reselling email infrastructure to their own customers. SendChief gives you the provisioning stack without months of build time — infrastructure-for-infrastructure.
SEO / PR link-building agencies
Link builders and digital PR teams doing outreach to journalists and publishers. Real webmail, calendars and IMAP mailboxes make replies land in a normal inbox — not a one-way relay.
Agency economics
Replace per-seat tools with one flat subscription
Drop in the shape of your book — clients and mailboxes per client — and compare what SendChief would cost against paying a per-seat ESP for the same number of inboxes.
Total: 80 mailboxes across 8 client workspaces. Compared against per-seat Google Workspace Business Standard at $14/user/mo.
