This comprehensive guide will walk you through the essential concepts and practical steps needed to master this topic. By the end of this article, you'll have a solid understanding of the key principles and be ready to implement them in your workflow.
Once your Sending Server is Running, you decide which campaigns use it. A campaign's email accounts then connect to their email providers through the server's dedicated IP address instead of Oppora's shared network.
This guide shows the three places you can pick a server, the two rules that keep each email account on a steady IP address, and what happens when a server isn't working.
Don't have a server yet? Start with What is a Sending Server?
The campaign builder has a Sending Server step right after Sending, where you pick your email accounts.

Need another server? Click Buy a server under the list.
When a new server finishes setup, Oppora asks "Your server is ready. Which campaign should use it?" Pick a campaign and click Continue. See Step 4 of What is a Sending Server?
Open the campaign and go to the Rules tab. Under Select accounts to send messages from you'll find the Sending server field.

Pick a different server, or None (Oppora default) to stop using a server for that campaign.
All the email accounts in a campaign send through the same server. To use different servers for different accounts, split them into separate campaigns.
An email account sends all of its email through one server at a time. Email providers like Google and Microsoft trust a mailbox more when it always connects from the same address, so Oppora won't let one account bounce between servers.
If you pick a server for a campaign and one of its email accounts already sends through a different server in another campaign, Oppora stops you and explains:

You can fix it in one click:
Next stays disabled until the conflict is fixed.
Your campaign keeps sending. If the server is down, stopped, restarting, or suspended for an unpaid invoice, the campaign's email accounts send from Oppora's shared network as usual. When the server is working again, they go back to it on their own. You don't need to change anything.
If you open the Sending Server step while the campaign's own server isn't working, Oppora tells you so. You can keep it selected, and the campaign returns to it once it recovers.
Does using a server change my daily limits, schedule or warmup? No. They work exactly as before. Only the network your email accounts connect from changes.
Can several campaigns share one server? Yes. Open the server to see which campaigns and how many email accounts use it, and how much it has sent this month against its recommended monthly limit.
I picked a server but the campaign still shows "Not available". What now? The campaign keeps sending without the server in the meantime. Open the server from Email Accounts → Sending Servers to see what's wrong, or see Sending Server billing, cancelling and actions if it was suspended for payment.
Renewals, invoices, failed payments, cancelling at period end, and what Start, Stop, Restart and Terminate do on a Sending Server.
Give your email accounts their own dedicated IP address. Here's what a Sending Server is, when to use one, and how to buy and set one up in Oppora.
