Problems Sending Mail

Hi Admin

i just got an email saying " Mail rate exceeded limit", and when I check my account it says I got no blocks. Please help me fix this issue, since I am having trouble contacting my clients... I made a mistake and sent a promotional email yesterday, because I did not know about Zoho Campaigns, but I already set that up, and now my promotional emails are being sent from there.

The email is  contacto@pixenfoto.com

Thank you!
