Add more leads to an active campaign (from a list or a new CSV)

You do not need to create a new campaign when you have more leads. Open the running campaign, add contacts from a saved list or a new CSV, and resume. New leads join the sequence from step 1; leads already in the campaign are not affected.

Prerequisites

• A launched campaign.
• Either a list already in Contacts, or a CSV ready to upload.

Steps

1. In Campaigns, select the campaign you want to add contacts to.

1. Click Contacts inside the campaign.

1. Click Upload Contacts.

1. Choose the source:

   • To use a saved list, select Lists and pick the list.

  - To upload new leads, click **Upload new CSV** and select your file. Map the columns as usual.

1. On the same screen you can add sender mailboxes. Add any extra mailboxes you want to send from now that the campaign has more leads.

1. Click Next.

1. Click Resume Campaign to put the campaign back into sending with the new leads.

The campaign's Contacts tab now shows the added leads with status Not contacted. They are picked up on the next sending window according to your daily new-contacts limit and sending strategy.

Tips

• Adding leads pauses the campaign while you edit. Always finish with Resume Campaign; if you close the editor early the campaign stays paused.
• If you add a large batch (for example 2,000 leads) and want your existing follow-ups to keep flowing, set the sending strategy to Follow-ups first or Balanced before resuming.
• Add sender mailboxes in proportion: roughly one warmed mailbox per 30–50 new emails per day.
• Leads that already exist in the campaign are not added twice.

Troubleshooting

• New leads are not getting emails: check the Daily new contacts limit in campaign Settings; if today's quota is already used, the new leads start tomorrow.
• Campaign shows as paused after adding leads: you did not click Resume Campaign. Open the campaign and resume it.
• List not visible under Lists: the list is empty or was created under Contacts after you opened the dialog. Close and reopen Upload Contacts.
