Mailient + Cal.com
A booking link asks the other person to do the work. With Cal.com connected, Mailient reads your real availability and offers times inside the reply.
Booking links solved scheduling for the sender and moved the work to the recipient. That trade is fine for a cold enquiry and slightly rude to a customer who asked a simple question and got a URL back.
Connecting Cal.com lets Mailient use the availability rules you have already set up, and answer with times instead of a link.
What Mailient does with Cal.com
Reads your real slots before answering
Mailient checks what is genuinely bookable against your Cal.com availability, so the times inside a draft are times someone can actually take.
Uses the right event type
It knows your event types — a 15-minute intro is not a 60-minute deep dive — and offers the one that fits what the thread is asking for.
Books the meeting, not just the link
Once you approve, the booking is created in Cal.com directly. The other person gets a confirmed time instead of homework.
Keeps track of what is booked
It can list existing bookings, so a proposal accounts for what you have already committed to this week.
Cancels cleanly when plans change
When something falls through, the booking can be cancelled through Cal.com so the slot reopens rather than sitting dead on your calendar.
How to connect Cal.com
Cal.com connects with an API key rather than an OAuth sign-in. You generate the key in your Cal.com settings and paste it into Mailient's Integrations panel — which means there is no consent screen and no third-party app to approve.

Cal.com integration FAQ
How does Mailient connect to Cal.com?
With an API key you generate in your Cal.com settings and paste into Mailient's Integrations panel. Unlike Gmail, Calendar, Notion and Slack, this is not an OAuth sign-in — there is no consent screen and no third-party app to approve in Cal.com. Revoking is a matter of deleting the key.
Should I use Cal.com or Google Calendar with Mailient?
They solve different halves. Google Calendar tells Mailient when you are free; Cal.com holds the event types and rules for how you want to be booked. If you already run scheduling through Cal.com, connect it — and connecting both gives the fullest picture of your week.
Will it book meetings without asking me?
Not by default. The reply proposing times waits for your approval, and the booking is created once you say yes. Autonomous action is a per-agent setting that is off unless you enable it.
Does it work with my existing event types and buffers?
Yes. Mailient reads the event types you have already configured rather than creating its own, so durations, buffers and availability rules you set in Cal.com continue to apply.
