We do not touch your email.
Though sending email through many web servers is possible, it’s unreliable and considered bad practice. This often leads to emails getting marked as spam or never being delivered.
These are hardly the qualities you’d want out of your email.
I strongly recommend using a dedicated email provider that will allow you to have custom-branded email addresses and ensure deliverability. Inboxes like this typically cost between $3 and $6 per inbox per month — which you would pay directly to the service provider.
