Hello,

I am writing in order to ask for help regarding the issue l am facing with. I am trying to send some emails to companies to promote my services, but after 15-20 sent emails I was unable to send emails anymore with this message pops up: 

What can I do to avoid this message and to continue to sending emails to potential clients? Can you advise me is there an option like that on Zoho? It's pretty urgent so I hope I'll heard from you soon!

Thank you,

Ivan
