Set the daily new-contacts limit for a campaign

The Daily new contacts limit caps how many leads a campaign contacts for the first time each day. It does not limit follow-ups; those are governed by the sequence delays and your mailbox limits. Use it to ramp a campaign gradually, keep total volume inside what your mailboxes can safely send, and avoid dumping a whole list on day one.

Steps

1. In Campaigns, select the campaign you want to adjust.

1. Click Edit Campaign.

1. Go to the campaign Settings.

1. Find Daily new contacts limit.

1. Enter the number of new leads the campaign may start each day. The default is 1,000; change it to your desired number.

1. Click Save.

1. Click Resume campaign to put the campaign back into sending.

The same setting is available at the Settings step when you create a new campaign.

How to choose the number

Work backwards from your mailboxes:

1. Count the warmed mailboxes attached to the campaign.
2. Multiply by the per-mailbox campaign limit (30–50 emails per day is safe for a warmed mailbox).
3. Reserve roughly half of that for follow-ups once the campaign is a week old.

Example: 10 mailboxes × 40 emails = 400 sends per day. Set the daily new-contacts limit to about 200 so that, with a three-step sequence, follow-ups fit in the remaining capacity.

Start lower for the first week of a new campaign (for example 50–100) and raise it once the bounce rate and reply categories look healthy.

Tips

• The limit resets each day in the campaign's sending schedule time zone.
• If several campaigns share the same mailboxes, the mailbox limit is what actually caps volume; the sum of the campaigns' daily new-contacts limits can exceed it without any harm, but the campaigns will contact fewer leads than the setting suggests.
• A limit of 1,000 with a small list simply means "as fast as the mailboxes allow".

Troubleshooting

• Campaign contacts fewer new leads than the limit: the mailboxes hit their own daily limits, the send window closed, or the sending strategy is prioritising follow-ups. See Daily sending limits: mailbox limit vs campaign limit.
• Change did not apply: you must click Save and then Resume campaign; leaving the editor without resuming keeps the campaign paused.
