What happens if the number of recipients for a campaign is larger than the amount of credits you have left

If you happen to be left with fewer credits in your account than the number of subscribers to whom you want to send an Email Marketing Campaign, then you should know that you will not be able to dispatch your email campaign. However, there is no need to let your eager subscribers wait, just buy more credits and move forward with your campaign dispatch. 

Remember, with Credits one credit equals one email sent to one recipient, so if you want to send a campaign to an email list of 60 recipients but only have 59 credits, you need at least 1 more credit before you should be able to dispatch your newsletter.

For this, it is a good idea to always check your remaining credits before sending out a campaign.
