Sending the rest of your campaign if you ran out of mailcredits
Without enough mailcredits, you cannot send a campaign. If you schedule multiple campaigns, they will be sent for as long as you still have credits. As soon as your credits run out, the remaining campaigns, or parts of them, will no longer be sent. In that case, not everyone will receive the campaign.
You can read what mailcredits cost and how to purchase them under subscription or not for occasional sending. How the price of a paid subscription is calculated can be found under how the price is determined.
Once you have topped up your credits, you can still send the campaign to the subscribers who did not receive it.
Creating a segment of the subscribers who did not receive the campaign
Sending a copy of the campaign to the segment
Copy the campaign by clicking ‘Copy’ next to the relevant campaign in the campaign overview. In step 2 of the copied campaign, select the segment you have just created. This contains the subscribers who did not receive the original campaign because you ran out of credits.
Repeat this for every list to which you want to resend the campaign.
You can read about how a campaign is sent from there and how quickly this happens in How newsletters are sent.
