How to add recipients to a campaign

You can add recipients to an email campaign in three different ways:

  • From Leads: select leads or a list of leads already saved in Hunter.

  • Upload a CSV: upload a CSV or TXT file, to import new leads and their attributes.

  • Manually: add new leads to a campaign by entering email addresses manually.

From leads: import from existing leads

Starting with the option to import From Leads, you can import existing leads in Hunter into your campaign's Audience section.

To find the specific leads you're looking for, you can apply multiple filters to help you narrow your search. The filtering options are very broad, with default options and specific ones based on the attributes you have associated with your leads.

Upload a CSV: import leads via CSV or TXT file

When choosing to import leads by uploading a CSV, you will be redirected to a new page where you can upload your file. The system will then prompt you to either select the destination list for your leads or provide the option to create a new Leads list.

👉 Existing leads will not be added to your list to prevent duplicates; instead, they will only be updated.

You can upload a CSV or TXT file. It's important to note that the file must use commas or semicolons as column delimiters. To be valid, your rows must contain at least an email column.

You also have the choice to request the system to verify the emails during the upload process. This will consume one verification credit per email verification.

💡When uploading a CSV file with more recipients than allowed in your plan for each campaign, the system will extract only the initial rows from your file, corresponding to the number of recipients allowed per campaign in your plan (e.g. 500 for a Free plan).

Manually: add email addresses manually

By choosing the option Manually, you can add the recipients manually by entering their email address, comma-separated, or one per line.

💡Keep in mind, that when doing so, they will be saved as Leads and when pasting more than 100 emails into the box, a new Leads import will be created.

The window you will get to manually enter email addresses to your campaign.

Verify your recipients

Once you have added your leads to your email campaign's Audience you can also verify the email addresses before launching your campaign, we will let you know the cost associated with the verifications.

Hunter will tell you the percentage of unverified emails in your Audience list and allow you to Test all unverified email addresses or verify single emails by clicking on Verify email.

Verifying your leads is part of a successful cold email outreach strategy as it will drastically reduce your bounce rate, increase your success and limit the risks of harming your email reputation.

Add leads to an existing campaign

To add new leads to an existing campaign, just go to the Audience section of your campaign and select + Add. This way you can add additional recipients to your campaign using one of the three methods explained previously.

As soon as a new lead is added to an active campaign, a new email is created and sent according to your sending schedule.

👉 If you a part of a Team, and you are not an Admin or the Owner of the subscription, keep in mind that you can only add leads to your own campaigns and not to campaigns created by other Team members.

Removed recipients: include manually removed recipients

🚨 Recipients that have been manually cancelled in a launched campaign can't be added again to the same campaign, even if you pause it.

In the case of a new campaign that has not been launched yet, when you manually cancel one or a few leads from your Campaign's Audience, you can include them again by deleting them from the "removed recipients" list.

To do so, go to the Audience section of your campaign and select "(Number) removed recipients" as shown in the screenshot below.

Now, simply click on Clear the list. This will free up the emails to add them again to the Campaign.

💡Keep in mind, that by design, bounced or unsubscribed leads won't be included again in any campaign and will end up directly in your Unsubscriptions list. More details on unsubscriptions can be found HERE.

Add leads to a campaign from the Leads section

Finally, you also have the option to add leads to a new or existing campaign, directly from the Leads section.

To do so, first select the chosen lead/s and simply click the Actions menu. Then select Add to a Campaign or Create a new Campaign, based on your preference, as shown in the image below.

How many recipients can be added to a campaign?

The amount of recipients that can be added to an email campaign varies based on your plan, however, there is no limit to the number of campaigns you can create.






Recipients per campaign



2,500 Recipients

5,000 Recipients

10,000 Recipients

👉 In case you have reached the limit of recipients per email campaign allowed in your plan, but need to add more, we simply suggest duplicating your campaign and adding the remaining leads to the new campaign.

If you are adding leads through a CSV upload, keep in mind that Hunter will always extract the initial rows from your file, corresponding to the number of recipients allowed per campaign in your plan (e.g. the first 500 for a Free plan).
