Your list grows. Your bill stays flat.
Run ten clients' email. Without ten messes to untangle.
Senderkit gives each client a clean, isolated workspace with its own database, domain, and billing. You manage them from one account. When a client takes email in-house, you hand them the keys — no data migration drama.
What slows you down today
Three bills that climb faster than your open rate.
Mixing client data in one Mailchimp account
One account, one brand, one shared risk profile. Multiply by 10 clients and you're one mistake away from a data-protection incident.
Separate logins, separate bills, separate chaos
Every client has their own login, plan tier, payment method. Reconciling it monthly eats a half-day.
Handovers are a nightmare
When a client goes in-house, you're exporting contacts, rebuilding templates, re-configuring domains. Three days of unbillable work.
What changes in week one
Same audience. Different economics.
Workspace per client, one login for you
Each client gets their own workspace with isolated subscribers, sending identities and API keys. You switch between them with one click.
BYOD per workspace
Plug each client's own Neon database into their workspace. Zero cross-contamination, zero compliance gymnastics.
Graceful handover
When a client takes email in-house: transfer workspace ownership, rotate API keys, done. The data's already in their database.
