Send emails from an alias
Mailshake sends your campaigns from one of the Google account's you've connected. By creating an alias in Gmail, you can send Mailshake campaigns from most any other email provider such us outlook.com. The video above walks through the whole process, but here are some frequently asked questions:
I'm getting an error in Gmail when trying to set up sending via my alias.
"You must send through outlook.com SMTP servers when you send as [email address]@outlook.com. However, this functionality is not available for your account. Please contact your domain administrator for more information."
This indicates that you need to enable an advanced security setting in your G Suite administrator console. Follow the video for step-by-step instructions, but essentially you need to check the "Allow per-user outbound gateways" setting.
Does this work with any email address?
Most email providers, yes. Your provider must allow connections over SMTP and either POP3 or IMAP. Sometimes these are settings that are off by default and you need to flip on. After turning them on, your email provider's help pages should give you the appropriate settings (such as host name and port number) that you'll need to enter inside Gmail.
Are there other ways to set this up?
In many email providers, you should be able to set up auto-forwarding so that all replies to your alias address are forwarded to your Google address. You'll still need the "Send mail as" setting hooked up in Gmail so that your Google account can send on behalf of that account, but auto-forwarding can eliminate the need for POP3 or IMAP. The key thing with auto-forwarding is that the email must come through without being modified or losing email headers.
What about company installations of Outlook?
We don't have a clear answer on this since each installation can vary so much. If POP3 and IMAP aren't allowed, you might be able to set up some kind of auto-forwarding rule. Here is a post answer that talks about how you can set up a "redirect" rule in Exchange to send a copy of messages to any email address.
