Shared inbox for agencies
The shared inbox for agencies that never forgets a client. Sektra keeps every approval, scope change and promise visible across dozens of retainers, and tells each account lead what needs them today.
Agency work is decided in email. Feedback rounds, scope changes, approvals and the occasional escalation arrive across several account leads, a studio address and, more and more, WhatsApp. None of it is labeled as a commitment, and much of it is one.
Sektra connects to the mailboxes and numbers your team already uses and builds a record of each client from the history already there. From then on it works the inbox. It ranks each thread by what it would cost to leave and assigns it to the right person. Every promise made in either direction goes on a list that only empties when the promise is kept.
The result is fewer Monday surprises. A retainer you asked Sektra to watch goes quiet for twelve days and you hear about it while a check-in still lands well. The deck promised on Thursday is due tomorrow, and the person who promised it already knows.
What it tells you, and why
“The revised deck you promised on Thursday is due tomorrow.”
Commitments are lifted out of the thread and tracked with their date, so a promise made in passing no longer depends on someone remembering it.
“No word from this retainer since the revisions went back twelve days ago. You asked to be told at ten.”
Ask Sektra to watch any retainer and it tells you the day the silence passes the number you set.
“Three people are on this approval thread and nobody owns it.”
Every thread gets an owner, by rule or by round robin, so client work stops living in CC lines.
What your team gets on day one
One inbox across Gmail, Outlook and WhatsApp
Studio addresses, account leads' mailboxes and the WhatsApp number clients use, in one place with one record per client.
A record per client
Scope, approvals, preferences and open questions for each account, built from email and available to whoever picks up the thread.
An assistant that follows through
Ask what was promised before a call. Tell it to remind you Thursday, or to watch a client and tell you when they go quiet.
Approvals with dates
Sign-offs and scope changes are lifted out of the thread with their dates, so when a client asks what they approved, the answer is one search away.
Questions, answered
What teams like yours ask before they connect an inbox.
Does Sektra replace our project management tool?
No. Sektra holds the client conversation across email and WhatsApp. Tasks stay in your project tool. Sektra makes sure the promise that created the task is tracked and the client hears back.
Can account leads keep their own inboxes?
Yes. Each seat can connect a personal mailbox alongside the shared ones. The record of each client is built across both, so a client's history is complete whichever address they wrote to.
How long until the record is useful?
Sektra reads the history you already have when a mailbox connects, and the record of your active clients is ready within the first hour. It deepens as new mail arrives.
Can an agency run WhatsApp and email in one inbox?
Yes. A WhatsApp Business number connects through your provider and sits next to the Gmail and Outlook mailboxes. A promise made on WhatsApp is tracked next to the one made by email.
Coming from another tool?
What stays the same, what changes, and what the switch takes, one tool at a time.
