Separate sending, clear lead trails for agencies

Think of the payment as covering two things: the wiring between apps and the space to run work inside your own accounts. The provider publishes three lifetime tiers on softwareprogrammer.app, named Starter lifetime, Growth lifetime and BYOK unlimited lifetime. Nothing in that list is priced per client, so your planning centres on volume rather than headcount.

A single connection screen is what you are really paying for. Each client's mailbox and records connect once, and after that the AI works inside those accounts rather than in a shared pool. That is the structural answer to your objection about one inbox mixing clients together, because the separation comes from whose account the step runs in, not from a label you apply afterwards.

The activity log is part of the same purchase. It records what ran, so when a client asks where a lead came from you can trace the step rather than reconstruct it from memory. Guided setup means you are not building connections from scratch, which matters when you have six or seven clients to bring on and limited hours between campaigns.

Budget thinking also has to include your own model usage if you pick the bring-your-own-key route. On that tier the model provider bills your key directly, so the lifetime payment covers the platform rather than the tokens. Keep that separate in your head before you compare tiers, because it changes what each month actually costs you.

Starter lifetime is the tier to test on one client first. You get the connection screen and the guided setup, and you can watch the activity log fill as the AI researches, writes, sends and updates records inside that client's accounts. Treat it as a way to prove the separation works before you move any other client across.

Growth lifetime is where a working agency usually settles, because the tiers are drawn by volume rather than by seats. More work running through the platform means more outreach, more research and more logging across your client list. The distinction from Starter is capacity, so match it to how much you actually push through in a week rather than to how many clients you have signed.

BYOK unlimited lifetime swaps a volume ceiling for your own model key. You supply the key, your provider bills the usage, and the platform does not meter your requests the same way. For an agency with steady volume and a model account already in place, that shape can suit better than counting runs. Check your provider's billing before you assume it is cheaper.

Across all three, the substance is the same: connections, work inside your accounts, guided setup and a log. What changes is how much you can push through and who carries the model cost. Read the tiers as capacity bands, not as feature gates, and you will choose more accurately for a small client roster.

The worry is a shared inbox that blends clients together, and the honest answer is that separation depends on how you connect accounts. Because work runs inside the accounts you connect, each client's sending happens in that client's own mailbox. If you connect one inbox for everything, you get the blended result you fear. Connect each client separately and the separation holds.

Permissions set the boundary. The platform can only reach what each connected account already allows, so an app your client has not authorised stays out of reach until someone grants access. That is a constraint, but it is also a safeguard: the AI cannot quietly step outside the accounts you wired up, and your client's data stays where their admin put it.

Destructive steps wait for your confirmation before they run, which means a sequence that deletes or overwrites records will pause for a person. Plan for that pause in anything that updates client data. For outreach, research and logging the flow is continuous; for changes that cannot be undone, you stay in the loop, and that is a reasonable trade for an agency handling other people's records.

Decide on evidence, not on enthusiasm. Run one client through Starter lifetime for a couple of weeks, watch the activity log, and check that every lead you send can be traced back to the step that produced it. If the trail holds and sending stayed separate, you have the proof you need to bring a second client across.

Then look at volume. If you are bumping against what Starter allows, Growth lifetime is the natural move because the tiers are drawn by how much work passes through. If your constraint is model cost rather than run count, and you already hold a key with a provider, BYOK unlimited lifetime is the shape to weigh instead. Neither choice is permanent in principle, but both are lifetime purchases, so decide once with real numbers in front of you.

Before you pay, check three things with your own eyes: that each client's accounts connect separately, that your team knows which steps need confirmation, and that you understand who bills the model on the tier you pick. If any of those is unclear, ask before buying rather than after. A lifetime tier rewards a decision you have already tested, not one you are still guessing at.
