Campaign settings

There are 4 sections in the Campaigns Settings: Sending window, Email accounts, Custom domain and Unsubscribe sentence.

How to change the Sending window?

The sending window is the window of time when emails in your campaigns can be sent. You can select on which days the emails will be sent, at what time, what the delay between each message sent will be, and the sending priority.

We recommend selecting at least two or more days to ensure that all your emails are sent in a timely manner.

The delay between emails can be between 30 and 600 seconds (10 minutes).

If the emails of your campaign can't all be sent on the same day, they will be sent on the next scheduled timeframe.

If you want the follow-ups in your campaigns to send in priority over sending initial messages to new recipients, make sure to check this option in the Sending priority section.

Please note that you can customize the sending window for each campaign if you want to. If you edit the sending window of a specific campaign, then editing the default sending window will not override the settings of that specific campaign.

Setting up the Email accounts

Set up an email account to send the emails.

The supported accounts are:

  • Gmail

  • Google Workspace

  • Outlook

  • Microsoft 365 Business

You can also connect the following number of email accounts based on your subscription:









Please note that this quota is counted at the team level: it's the total number of email accounts that team members can connect in Campaigns.

To further customize a connected email account, click on the "Edit" link next to it.

Each email can have its own daily sending limit, which must be between 1 and 400 emails for Google accounts, and between 1 and 250 emails for Microsoft accounts.

If you connected a Google account, you will have two further customizations possible: 1) If you have aliases set up on your Google account, you can select one of your aliases to send the emails from; 2) you can edit the sender name which will be visible in the from field of your send emails.

The Hunter Campaigns can only be connected to Gmail/Google and Outlook/Microsoft accounts. However, if you have a professional email address set up with a different provider, it can be possible to set up an alias on a Google account which links to your other provider via SMTP. Google has written a help article that explains how aliases can be set up here.

Please note that when sending campaigns with an alias, the replies and bounces might not be detected in Hunter as Hunter only has access to the Google account.

Email Sender Account Rotation

Starting with our Starter Plan, Hunter offers the possibility to rotate the sender email accounts for a campaign. This helps with keeping your daily sending limit low and increasing the email deliverability, limiting this way the risk of getting your account blocked by your email provider.

ℹ️ To use this feature you will need at least two email accounts to be set up, see how to add an additional account in your Campaign Settings or have additional members in your Team.

To add an additional email account, simply click on the "From" sender box and select the account you wish to add.

In case you do not have an additional account connected to Campaigns yet, simply click on "Add an account" below the sender box and you will be immediately directed to the email account Settings, in order to add an additional account/s.

Once configured the emails will be sent out in rotation to the recipients, switching between the chosen sender email accounts, in respect of each account's daily sending limit.

Entering your Custom domain

If you are on a Growth plan or above, you can enter your own custom domain to track the openings and clicks inside of your campaigns. This will help you monitor your deliverability and sending reputation more closely.

You will find a full help guide on how to set up your own custom tracking domain here.

Editing the Unsubscribe sentence

Here, you can edit the unsubscribe sentence at the bottom of the email:

Reuse your Campaign content

To use the same email content multiple times, you can save your content in Templates, or duplicate an entire campaign's content.

How to Create and manage email templates?

In the Templates section, you can create new templates to use for your campaigns and edit or delete existing ones.

To find inspiration, click on "Browse templates" next to the "+ New template" button, and look at our templates catalog to directly save the ones you are interested in to your account:

All your templates will be available to copy directly in the content of a campaign when you create it:

How to Duplicate a Campaign?

To duplicate an entire campaign's content, go to the Campaign's page, and click on its name. In the menu that appears, click on "Duplicate".

You will automatically be redirected to a new campaign with the exact same duplicated email content, including any follow-ups you may have. However, the audience will not be duplicated.

How to Update active Campaigns?

Once a campaign is active, it's possible to add new recipients to it. This allows you to send the same message to new leads without creating a duplicated campaign.

You can also add recipients directly from a list of lists. Select the lead(s) you want to add, and from the Action menu, click on Add to a campaign.

As soon as a new lead or an email is added to an active campaign, a new recipient will be automatically added to the campaign, and an email created and sent according to your sending schedule.

How to Add a follow-up?

It's possible to add follow-up(s) once a Campaign is Active.

To do that, you can pause it first.

Then, click on the Content section, and click on the Add a follow-up button.

Once you finish adding your follow-up(s), you can resume your Campaign by toggling it On.

What are Unsubscriptions?

All the leads that have unsubscribed from an email campaign will be directly added to the Unsubscription list. This also means when a recipient unsubscribes from an email, the unsubscribe preference is applied on the Hunter account level to ensure the recipient's preference will be applied to all email accounts used to send emails.

All bounced emails are automatically added to the unsubscription list, too. This means that these email addresses cannot be contacted again, even if you add them to a campaign by mistake.

It is possible to manually add new emails or domains to unsubscribe:

You can also download the unsubscribed emails or domains in a CSV file.

How to integrate your Campaign?

If you'd like to integrate your campaigns with other tools, there are a couple of options available for you.


You can use Zapier to easily build integrations with many more online apps. With Zapier, you can check when an email is opened or read, or when a campaign is created. You can also create a lead and a recipient in an existing campaign.

You can find out more about how to integrate Hunter's Campaigns with Zapier, please take a look at the following Zapier help guide.


Webhooks are notifications about various events that occur for your sent emails in Hunter Campaigns. These notifications can be used to integrate Hunter Campaigns with other applications.

When you create a webhook, it will send a POST request to the URL of your choice whenever the chosen event happens. There are 4 events you can use:

  • Email sent

  • Email opened

  • Email clicked

  • Email replied

Webhooks can be configured to be added to all your campaigns by default, or you can create a webhook linked to a specific campaign only.

To learn more about our Campaign webhooks and how to set them up in your Campaigns, check the following article:


You can also use our API to perform some actions or retrieve direct information from your campaigns. For instance, you can add or cancel a recipient in a campaign, you can list all your campaigns and you can list the recipients of a campaign.

You can read our API documentation for Campaigns here.
