Seeing significant interest in the dedicated IPs, we have updated the program to allow AppSumo customers to add a dedicated IP address to their plan at a discounted monthly rate of $19.99. You can contact SocketLabs support to add this feature. In addition, the full StreamScore detail view is available with three codes. In addition, to allow Sumolings a way to send beyond 75k messages, we’re offering the ability to add on “additional messages” at our Basic Plan additional message rate. Lastly, we are offering a 20% lifetime discount when you upgrade to any of our Pro or above plans. All of these features are accessible by contacting support.

Will I be able to send up to my message limit as soon as my account is provisioned?

SocketLabs’ goal is to give your messages the highest odds of reaching the recipient's inbox. This requires us to establish a strong reputation for your email with mailbox providers. Accomplishing this requires us to initially throttle the rate at which we deliver your email. This is an automatic "warm-up" process that gets the mailbox providers (i.e. Gmail, Yahoo, Microsoft, etc...) familiar with your email, without bombarding them with too much too soon. You will notice your messages being delivered increasingly faster over the first few weeks of your service as the warm-up period progresses.

We discuss the warm-up process more in depth here in our Help Center (https://help.socketlabs.com/docs/warm-up-period).

What is a whitelisted authentication IP?

First, let me say this is different from a dedicated outbound sending IP. A whitelisted authentication IP allows you use a source application's IP address as the login credentials when the app/website does not support usernames and passwords. We customize the account to recognize and accept the incoming mail that originates from that IP address.

It is not related to a dedicated outbound sending IP which provides a unique IP address from which to send email. This allows a sender to control and develop their own sending reputation free from the potential effects of other senders.
