Can you use a Gmail | Hotmail | Yahoo email address as the sender of your campaigns

You are more than welcome to register for an account in our platform using your Gmail / Hotmail / Yahoo email address. Please note that you can even send out your email marketing campaigns to your email lists, using the aforementioned email as a sender.

However, keep in mind that a personal address, such as the ones provided by Gmail, Hotmail, and Yahoo, is very likely to have your email campaigns considered as Spam from various filters used by email service providers such as Gmail, Hotmail, Yahoo, and others. 
Email service providers consider newsletter campaigns as something only professionals do and so they won't allow any such emails to be properly delivered if the sender email is a non-professional one. To this end, we strongly urge you to register for our platform's services using a professional email address - one that will easily be recognized by your recipients.

If you have already registered using your personal address, you can always add a new sender to your account, using your professional email address this time. After you verify the new sender address, you will be free to proceed with the dispatch of your first campaigns using your professional email address as the sender if you prefer to do so.
