Trellus for SmartleadThe Smartlead dialer for campaign leads and the call queue
Trellus is a Chrome extension that adds power dialing and parallel dialing (up to five lines at once on eligible plans) to Smartlead. Call a campaign's leads, the All Leads list, the call queue or a single lead. Unsubscribed and blocked leads are skipped, and each call is saved as a note on the lead.
Where Trellus works in Smartlead
The Smartlead pages Trellus uses
Trellus works from the Smartlead pages that list leads. Other saved lists under CRM are not supported today.
Open a campaign and its leads list. Trellus reuses the filters the page is showing and any rows you selected.
The All Leads list under CRM works the same way: filter or select in Smartlead, then start the session.
From the call queue of Smartlead's dialer, Trellus calls the queued leads and, once a call is logged, moves the lead to the next step of its sequence.
On a lead's page, and on a lead opened from the master inbox, the call button places a one-off Trellus call.
From the leads list to the lead note
Open the leads you want to call
Use a campaign's leads, All Leads or the call queue with the Smartlead filters you already use, or tick the rows you want.
Trellus leaves out who should not be called
Leads marked unsubscribed, blocked or Do Not Contact are skipped, along with leads Trellus cannot check and numbers shorter than ten digits.
Choose power or parallel
Call one lead at a time, or dial several at once and talk to whoever answers first.
Save the call to the lead
Trellus adds a note to the lead with the summary, disposition, number called, duration and links to the recording and the transcript.
What Trellus saves in Smartlead
Trellus saves the note with the rep's signed-in Smartlead session, so there is no Smartlead API key to paste. When the call's disposition is one of your Smartlead lead categories, Trellus also sets that category on the lead.
Phone the leads your emails already reached
Priya filters a campaign's leads to the people she wants to phone today and starts a Trellus session on that list. One lead has unsubscribed, so Trellus leaves it out. She dials the rest with parallel dialing and talks to whoever answers.
The lead has a new note with the summary, disposition, number, duration and links to the recording and transcript. Her disposition was Interested, which is also one of her Smartlead lead categories, so the lead's category now reads Interested.
Who this fits
Trellus fits a team that sends email from Smartlead and wants to phone the same leads on more than one line at a time, keeping the result on the lead. It is a poor fit if callbacks must be created inside Smartlead, or if the numbers you call are kept in custom fields and not in the lead's phone number field.
Smartlead and Trellus
Where does Trellus work in Smartlead?
On a campaign's leads list, the All Leads list under CRM, the dialer's call queue, a single lead's page and a lead opened from the master inbox.
Does Smartlead have a dialer?
Yes. Smartlead sells SmartDialer as an add-on. Its product page describes it as a power dialer that "dials your selected leads one at a time, never several at once" (Smartlead power dialer page, checked November 2026). Trellus adds parallel dialing, up to five lines at once on eligible plans, to the same leads.
Do I need a Smartlead API key?
No. Trellus works in the browser with the Smartlead session the rep is signed in to. Nothing is pasted into Trellus settings.
Which phone number does Trellus dial?
The phone number field on the Smartlead lead. Each lead has one number. Phone numbers kept in custom fields are not read, and numbers shorter than ten digits are skipped.
Does Trellus skip unsubscribed leads?
Yes. A lead that is unsubscribed, blocked or marked Do Not Contact is left out of a session, and calling one directly is refused.
What does Trellus write to Smartlead?
A note on the lead with the summary, disposition, number called, duration and links to the recording and the transcript. If the disposition has the same name as one of your Smartlead lead categories, Trellus sets that category. For a lead called from the call queue, Trellus moves it to the next step of its sequence.
Does Trellus create callbacks or tasks in Smartlead?
No. Trellus saves the note and, where it applies, the lead category. It does not create a task, a reminder or a callback in Smartlead.
What if a lead is in more than one campaign?
Trellus asks the rep to choose the campaign before calling, so the note is saved against the right one.
How much does Trellus cost for Smartlead?
Power is $99.99 per seat per month and dials one number at a time. Power + Parallel is $149.99 per seat per month and dials several numbers at once, up to five lines on eligible plans. Business is custom. You can buy a single seat online, with no seat minimum. See current pricing.
