How To Request and Configure a Dedicated IP

A dedicated IP address is an IP address that is associated with only one account — yours. By default, you share the IP with other Selzy users which means that your sender's reputation and deliverability rate depend on other users sending emails from the same pool of IPs. For example, if users you share your IPs with start sending spam campaigns and get blacklisted or banned on a certain territory, your campaigns will be affected as well. 

If you want to control your own deliverability and your sender’s reputation, you can purchase a dedicated IP from Selzy. It is an additional feature for your account, and you will be charged for it separately.


The setup cost for one IP is $20. Plus, you will need to pay $40 a month per server for this service. Note that to use a dedicated IP, you need to authenticate your domain.

Requesting a dedicated IP, you take full responsibility for its use. You must send email campaigns in compliance with Selzy’s Anti-Spam Policy. Otherwise, your deliverability will decrease.

Note that we can not restore your sender’s reputation. Once it is damaged by campaigns violating the Policy, it will take time and effort on your part to restore it. 

Set up a dedicated IP

Calculate how many IPs you need

For best results, you need to calculate the number of IPs for the domain based on the number of email campaigns you are planning to send. Selzy guarantees a speed of at least 70,000 emails per hour from one warmed-up IP. This can range from 70,000 to 100,000,  depending on the amount of email campaigns and email providers you send your emails to.


You can calculate how many IP addresses you will need using this formula:

Number of email sends per day / 85,000 (average number of emails per hour) = Number of IPs needed (rounded up).

For example, you send 10 million emails per month. That would be about 333,333 emails per day.

333,333/85,000=3,9. That means you need 4 IPs.

Depending on the topic of your campaigns, our specialists may recommend connecting more IP addresses to ensure smooth email sending. For example, email campaigns about loans or betting are at higher risk for spam complaints, so the Selzy team may recommend using more IPs. 

Please note that in all circumstances, the Selzy team acts for the benefit and in the interests of our clients. We would never impose unnecessary services, and if our specialist considers it necessary to add a few IP addresses to your pool, there are good reasons for that.

Our anti-spam service regularly controls and monitors the deliverability of all email campaigns. Depending on the current state of email services operations and Selzy’s Anti-Spam Policy, Selzy can update the mechanics of calculating the required number of dedicated IPs for each specific case.

Set up a dedicated IP

To start using a dedicated IP you need to request it, configure it, and wait for it to be enabled by our specialists. The initial setup can range from 15 minutes to 72 hours depending on the domain you use. Afterward, Selzy’s specialists will enable the IP within 48 hours.

The cost of setting up one IP is $20. Also, you will be charged $40 per IP for a month of use. You can request a dedicated IP in your personal account by clicking Add:

To access the dedicated IP page, click on your account and select Dedicated IP for campaigns. Then click Add.

Next, you will see a dedicated IP request window where you need to specify the name of the domain, the number of servers, and what to do in case of technical issues. There, you will also see the amount to pay for the setup and monthly usage. 

Note that you won’t be able to send the request if you do not have enough funds on your balance to cover the payment amount. Upon sending the request, you will be charged the cost of connection ($20 per server). After the setup, you will be charged the monthly cost ($40 per server).

A dedicated IP request window with the cost of connection in red and You have insufficient funds to submit an application note at the bottom.

First, specify the name of the domain for a dedicated IP. For example,

Specify the name of your domain name first.

Next, specify the needed number of servers you calculated on the previous step. It can range from 1 to 5 depending on your needs. 

Then, select what the system should do if there are technical issues with a dedicated server. The system can either use a common pool of IPs instead of the dedicated one or wait for the dedicated IP server’s recovery. In the latter case, your sending will be paused. This setting applies to all of your servers.


Once you have specified the name of your domain name and mode of work in case of technical issues, these parameters can not be changed after the setup is done.

Enter DNS records for configuration

After you have specified all the needed information, click the Make a request button.

After requesting a dedicated IP, you will see the records you need to add to your domain hosting (DNS zone). Here you can see the record types and records to add: 

Settings for the DNS server are shown with details about settings checks that occur automatically every 6 hours. The dedicated IP will be configured within 48 hours after the addition of the DNS settings.


For the dedicated IP to work, you need to add DNS records and have domain authentication configured as well. If you have not done it yet, follow the domain authentication instructions.

Log in to your domain hosting and add the provided DNS records. 

Let's look at how to add entries using DirectAdmin as an example. You can also add entries to another control panel, but the interface will be different.

On the main page of your hosting control panel go to the Account ManagerDNS Management where you can manage DNS records of the domain.

The main page of the hosting control panel at DirectAdmin

Control panel in DirectAdmin

On the DNS Management page, click the Add Record button to add a new record.

Сlick the Add Record button

Add all CNAME records one by one. To do this, copy the values ​​from the Selzy account settings and add them to the appropriate fields.

Create a record of type CNAME

Then you need to add include:uni.yourdomain (from Selzy account settings) to the SPF record.

Click on the edit icon next to the SPF entry.

How to edit SPF record

The merged SPF record will look like this:

SPF recording settings

After you have entered the records on your domain hosting, you can check whether they are added correctly by clicking on the Check settings button. 

If the records are entered incorrectly, the system will display them in red. You can see an example below:

Click on the Check settings button to check whether the records were added correctly. The records on the image are shown in red which means they were not added correctly.

If the records are added correctly, they will be displayed in green. 

After you have entered the DNS records on your domain hosting, the setup is complete. If there are enough funds in your account to complete the payment and all settings are correct, the Selzy specialists will activate the dedicated IP within 48 hours. 

You will see that the IP status has changed to Active. This means that it is activated and works correctly.

You can see the IP status in the Dedicated IP for campaigns section of your account. The Active status means that the IP is working correctly.

However, before you can use your dedicated IP in full, you need to complete the warm-up process.

Warm up your dedicated IP

For your dedicated IP to work correctly and gradually get a good reputation, it needs to be warmed up. A good reputation of your IP address will maximize the delivery of email campaigns and minimize the risk that it will be spammed or rejected.  

The warm-up period is 40 days. For each individual IP, it starts at about 50 emails per hour per email service (Gmail, Yahoo, etc.) in the first few days. Then the email sends are gradually increased by the system automatically.

In the table below you can see how the IP warm-up will take place. The table shows how the amount of emails sent will increase depending on the warm-up day. 

Day Gmail, email per hour Yahoo, email per hour
1 48 48
2 57 57
8 255 255
15 1,100 1,100
23 12,000 2,500
28 47,000 5,000
35 Without limitation 10,000
40 Without limitation Without limitation

Additional information about the warm-up: 

  • Warm-up only applies to sending to public domains (Gmail, Hotmail, etc.). For corporate domains, sending during warm-up is done from a common IP pool.
  • If during warm-up you send an email campaign that would take more than 1-2 hours to send due to warm-up limits, a part of the campaign will be sent from the common IP pool. This is done to speed up the sending, otherwise, such a campaign may take tens of hours to send.

When running a dedicated IP warm-up, it is important to send an email campaign every day. This will help to warm up the IP and ensure that it works properly in the future. 

After the warm-up process is complete, all limits are removed, which means that you can fully use your dedicated IP addresses.

Payment for a dedicated IP

As mentioned above, when requesting a dedicated IP, $20 will be charged to your account per server. After you set it up, the Selzy team will activate the dedicated IP and you will be charged $40 per server for the first month of use.

Going forward, you will be charged $40 per server every month. For example, you activated one dedicated IP server on August 20th. You paid $60: $20 for the connection and $40 as a monthly payment. On September 20th, you will be charged $40, and so on. 

If there is no money on your balance to pay for the dedicated IP for the next month, the dedicated IP will be suspended and a notification email will be sent to you. 

You will have 5 days to top up your account to continue using the dedicated IP. If you top up your account within 5 days after the notification email, the dedicated IP continues to work normally. If the account is not topped up within 5 days after the notification email, the dedicated IP will be set for disconnection. 

Restoring a dedicated IP

If there is no money on the account to pay for the dedicated IP, it will eventually be disconnected. 

If you top up your balance within 5 days, your dedicated IP will start working automatically. After 5 days, your IP will be set for disconnection. If you top up your balance after 5 days of the payment date but before 35 days, you need to manually resume the IP as described below. If your dedicated IP has not been paid for and restored within 35 days, it will be completely deactivated. 

If you need a new IP in the future, you can request it by accessing the Dedicated IP for campaigns section of your Account. There, you will be able to click the Restore button. But you will be assigned a new IP since your previous IP has been completely deactivated. 

If you request to restore your IP after 35 days, you will be charged 2 payments again. Per IP: $20 for setting up a dedicated IP and a $40 payment for the first month of use.

To restore the work of the dedicated IP, you need to top up your account and click the Resume button. The system automatically checks for funds to make a payment on your balance (2 times a day) and initiates the withdrawal of money for the dedicated IP. But if you press the button, it will help to speed up the process of the dedicated IP recovery.

 After you top up your balance, go to Dedicated IP for campaigns and click on Resume to continue using your dedicated IP.

After the IP is restored, it will start working within 24 hours. 

Deactivating a dedicated IP

If you no longer need a dedicated IP, you can deactivate it. From your Account, select Dedicated IP for campaigns. Click on the Disable button to deactivate the IP, and it will be deactivated within 24 hours. If you have several dedicated IPs, you can deactivate each one separately.

Go to Dedicated IP for campaigns and click on Disable to deactivate your dedicated IP.

We advise you to deactivate the IP a day before the date of monthly payment for its use. This will ensure that no accidental payment is charged after the IP is deactivated. 

If you are charged after the IP has been deactivated, please contact our support team to request a refund.
