Calling hours are per region
A single global window is the wrong answer for a campaign spanning three time zones. We set the hours per region and per campaign, so nobody is called at breakfast.

Retell AI and lemlist integration
Your sequences run across time zones and your team does not. We connect lemlist to a Retell AI voice agent so the call step still happens when the prospect’s afternoon is your midnight, and the outcome lands on the lead. It is a one-time setup by our team, not a monthly middleware subscription.
- From $100, one-time setup
- No monthly fees from us
- Tested on your own calls before go-live

The sequence keeps their hours. Your team keeps yours.
A lemlist campaign is scheduled around the prospect: sends land in their morning, and the call step is set for a sensible hour in their day. If you are selling into three regions, a good chunk of those steps come due while your office is dark. They pile up overnight and get worked at whatever time your reps start, which is usually the wrong time for the person being called.
A Retell AI agent does not mind. It takes the call step in the prospect’s own working hours, asks your qualifying questions and books into a real calendar, then writes the summary back onto the lead so the sequence knows whether to keep going. Your reps arrive to booked meetings and qualified notes instead of a backlog of tasks that are now badly timed.
- Teams selling into other regionsCall steps happen in the prospect’s day, not yours.
- Replies that land overnightAn interested reply at 2am gets a call in their morning.
- Small teams with big listsFirst contact happens at volume; reps take the qualified ones.

A one-time setup, not a monthly middleware bill
We are not a middleware. We plan the connection, set it up, test it on your calls and hand it over.

Your team fixes the broken steps
Where a small connector layer is the most reliable route, we say so in your written scope, set it up in your own account and choose the option with the lowest running cost.
Where Retell AI and lemlist setups usually go wrong
The call step has to close
If the task stays open after the call, the sequence stalls. Every outcome closes it, including the ones where nobody answered.
Calling only who agreed to be called
Not every lead in a cold sequence should get a phone call. We agree exactly which steps and reply categories trigger one before anything goes live, and you and your counsel set the rule.
Concurrency and bursts
A standard Retell AI account includes twenty concurrent calls, with more charged per concurrent call per month. We pace the queue so a regional spike does not need extra concurrency to work.
How we set it up
- 1
Agree the call rules
Which campaigns and steps trigger a call, the hours per region, what the agent asks, and what each outcome changes in lemlist. You get a written scope with a fixed one-time price.
- 2
Access for the setup
Team access to lemlist and access to your Retell AI account and agent. Nothing for your team to install.
- 3
We connect and test
We push test leads through the call step in each region, take the calls ourselves, and check every status, note, closed step and stopped sequence.

Questions about Retell AI and lemlist
Can a Retell AI agent work lemlist call steps?
Yes. A lead reaching a call step is called by your agent within the hours set for its region, and the outcome closes the step and updates the lead.
Can it call outside our office hours?
That is the main reason to do this. The agent works the prospect’s hours, not yours, within whatever windows you set per region.
Does the sequence stop after the call?
When the outcome says it should. A booked meeting or a clear no stops it; a no answer closes the step and lets the sequence carry on.
Is there a monthly fee?
No. You pay once for the setup. Unlike Zapier, Make and similar middleware subscriptions, there is no monthly or per-task charge from us. Your lemlist and Retell AI plans are unchanged.
