Hunter sends sequence emails from a sending queue. That queue follows your step delays, sending window, and each sender account’s daily sending limit (plus account rotation if you use multiple senders).
This article explains how Email Sequences scheduling works so you can understand when sends happen and what affects timing.
What happens when a sequence starts?
Once your sequence is "Active" , Hunter begins preparing emails for each recipient and sending them automatically when they’re due. Preparing emails may take up to 15 minutes.
Emails may not send immediately, Hunter follows your sequence timing and sending settings.
You can track what’s coming next in the Current state column in the sequences list.
Emails are sent progressively at a controlled pace, without sending outside your allowed hours.
By default a 30 second delay is set between each email sent. You can edit this here.
How the sending queue works
Hunter sends sequence emails from a queue. When a step becomes due for a recipient, it’s added to the queue and sent when the following conditions are met:
Step delay: the wait time since the previous step has passed
Sending window: it’s currently within your allowed days/hours
Daily sending limit: the sender account still has sends available today
Sender availability: the sender account is connected and usable (or another sender can be used via rotation)
💡 The key rule: older scheduled emails always go first.
If multiple sequences share the same sending account, the oldest active sequence has priority.
What this means in practice:
If Sequence A started before Sequence B, Sequence A will use the sender’s capacity first
Newer sequences may pause temporarily until earlier ones finish sending
ℹ️ With Email Rotation, Hunter distributes recipients evenly between multiple sender accounts, allowing emails to send simultaneously instead of waiting in a single queue.
Daily Limits & Sending Window
Hunter sends emails automatically, but only if:
Your sender account hasn’t reached its daily limit yet
The current time is within your sending window
Daily sending limits
Each connected sending account has a daily maximum, shared across all sequences using it.
Limits apply per sender account, not per sequence
If you have multiple senders, your total daily capacity is the sum of all sender accounts limits
Hunter keeps the default limit low (15/day) to protect deliverability, although it can be increased as you scale your outreach, from your Email accounts center page.
Or directly in the Settings tab of a sequence:
Sending window
Sequences only send during your configured sending days and hours.
You can set a default sending window for your account from your Sequence Settings page, and optionally adjust it for individual sequences.
If an email can’t be sent within your window, Hunter pauses and resumes on the next allowed day.
Progression column explained
On the main Sequence page, the Progression column shows how far your sequence has progressed through its steps.
Each bar represents a step in the sequence (e.g., Email 1, Follow-up 1, etc.).
It’s a step-by-step progress view, showing how many emails have been sent in that step and how many are still left to send.
Hovering over the bars reveals a tooltip with the breakdown per step.
The Progression column doesn’t indicate whether a sequence is currently “waiting” or “actively sending.” For that, check the Status and Current State columns. Sequence statuses are detailed in this article.
Current state
In the Current State column, Hunter shows an estimated next sending time, based on the current state of your sequences and your current settings.
That estimate can change depending on:
other sequences ahead in the queue
daily sending limits
your sending window settings
your scheduling perferences
