What happens if the number of recipients for a campaign is larger than the amount of credits I have left in my Pay As You Go plan?

If you happen to be left with less credits in your account than the number of subscribers who you want to send an Email Marketing Campaign to, then you won't be able to dispatch your email campaign. Don't let your eager subscribers waiting, grab more credits and move forward with your campaign dispatch. 

Remember, in a Pay-as-you-Go Plan one credit equals one email sent to one recipient, so if you want to send a campaign to a mailing list of 60 recipients but only have 59 credits, you need at least 1 more credit before you'll be able to dispatch your newsletter.

It's a good idea to always check your remaining credits before sending a campaign!
