Is there any limit on sending email invitation from SMTP?

Service providers usually sets a limit on SMTP for sending emails. Please check with your service providers for any such limits on daily or monthly basis.

For Example: Gmail has a SMTP limit of 500 emails per day. If you want to send 1000 email invitations, you need to divide your list in 2 (500 each) and then send one list per day.

Does my IT have to do anything?

It depends - but very likely yes. The way the SMTP Relay system works is that, your servers will be the initial receivers of the email - even if the email is not destined to your domain. This makes sure that your servers are the initial point of contact as they email out to the wider world.

Your IT staff may want to know the IP address from which we'll be sending emails (to be allowed to relay.) - Please click here to get a list of the IP addresses for our outbound servers.

How is this different than just whitelisting IP addresses in our mail servers?

By using the SMTP Relay, all emails that you send are routed through your servers. For example, if you are sending email invitations to gmail, hotmail etc. - and you would want to route all the emails through your servers - for corporate accountability, standards, archiving etc. - the SMTP Relay functionality will make sure this happens.

A list of SMTP servers:
