What is a Brand in MailBluster, and can I use the same email ID for multiple brands?

Last update: July 18, 2024

Each Brand in MailBluster represents a unique business or organization. So, if you have multiple Brands in MailBluster and want to store the same leads in each brand, then you can do that. It will not be considered a duplicate. Duplicate leads is only considered when you try to save same lead (email id) twice in each brand.

How can I use the same AWS account as Brand A for the Brand B?

Last update: September 12, 2024

It seems that Brand A was not created by you, while Brand B was created by someone else. MailBluster allows the same AWS account to be connected to multiple brands, but all those brands must be under the same MailBluster account. In your case, the ownership of these two brands is different, which is why you are unable to connect the same AWS account to both brands.

If you’d like to change brand ownership, our support team can assist with that, so both brands can exist under the same MailBluster account. After that, you’ll be able to use the same AWS account for both brands.

What to do if the default Unsubscribe link and the default View in browser link are both being flagged as phishing sites?

Last update: March 18, 2024

MailBluster uses mbmai1.com to generate the web version, subscribe, and unsubscribe URLs. As this domain is used by default for most MailBluster customers, its reputation has significantly diminished, affecting all email campaigns. As everyone knows email marketing is a tool that many scammers, and spammers use a lot and MailBluster is also used for that. MailBluster tries to prevent them, but it’s not possible to block them 100%. The result is a low reputation of the unsubscribe domain and leading to issues like the default “Unsubscribed link” page not opening.

To resolve this issue, you need to change the default auto-generated URL from MailBluster. To change the default auto-generated URL, navigate to the Settings > Custom URL page and set the Action URL. Additionally, ensure you create a simple CNAME record in your domain’s DNS configuration. Once the Action URL is set, MailBluster will use it instead of the default one. For instance, your Action URL could be: http://email.example.com where http://example.com is your domain.

If you’re not using Cloudflare for DNS, you must use the HTTP protocol for your Action URL. The Action URL in MailBluster will update both the web version and the Unsubscribe URL in your email campaign, resolving the issue.

After setting the Action URL in MailBluster, ensure it’s functional before sending any email campaigns. You can test this by accessing the Action URL from your web browser.

Can I remove the MailBluster branding from Double opt-in emails?

How to set Action URL for your Brand in MailBluster?

Last update: April 29, 2024

When MailBluster adds subscribe URL to your double opt-in email, unsubscribe URL and web version URL to your campaign email, it adds a link of its own domain.

You need to set the Action URL if you want to change the default URL and replace it with your own. It accepts a domain/subdomain. For example, you can set it to http://subdomain.domain.com, and MailBluster will use this domain as an Action URL. You can set it from the Brand>Settings>Custom URL tab of MailBluster.

Setting up Action URL

If the DNS of your website is not Cloudflare, you must use HTTP protocol for your Action URL.

You also need to set a CNAME record that points to MailBluster’s domain custom.mbmail1.com. You will be instructed accordingly on the process like the one shown below:

Setting up CNAME record using Name and Value/Target for the Action URL DNS records

After setting the Action URL, you can test the behavior by sending test emails to yourself.

If you use Cloudflare for your domain then use the following settings:

Using HTTP in Action URL:

  1. Set http://subdomain.domain.com as Action URL on MailBluster
  2. Create a new CNAME record http://subdomain.domain.com on Cloudflare that points to custom.mbmail1.com.
  3. Disable Cloudflare proxy for this record.
  4. It might take some time to propagate the record. You can try visiting http://subdomain.domain.com in your web browser to check if it’s propagated. If propagated, a page not found page of MailBluster should get displayed.
  5. Once DNS propagation is done (maximum 48 hours), send a test email and check the web version and unsubscribe links.

Using HTTPS in Action URL:

  1. Set https://subdomain.domain.com as Action URL on MailBluster
  2. Create a new CNAME record https://subdomain.domain.com on Cloudflare that points to custom.mbmail1.com.
  3. Enable Cloudflare proxy for this record.
  4. It might take some time to propagate the record. You can try visiting https://subdomain.domain.com in browser to check if it’s propagated. If propagated, a page not found page of MailBluster should get displayed.
  5. Once DNS propagation is done (maximum 48 hours), send a test email and check the web version and unsubscribe links.

Both cases will work if you use Cloudflare for your domain.

If your https is still not active yet in your domain, then you need to use http in Action URL instead.

Once you set the Action URL, please make sure it’s working before sending your next campaign. You can test this by simply sending a test email campaign to yourself and check the behaviour. If you see this then you are good to go:

How to set Unsubscribe Redirection URL for your Brand in MailBluster?

Last update: March 18, 2024

When you set the Unsubscribe redirection URL from Settings > Custom URL, it will redirect the receiver to MailBluster default domain after clicking the unsubscribe from your email content, and then after confirming the  Yes, unsubscribe button, it redirects you to the domain you set for Unsubscribe Redirection URL.

Here is an example on how to set Unsubscribe redirection URL:

Click on Settings and then on Custom URL. Then place the redirection URL link under Unsubscribe redirection URL

Here is an example of an Unsubscribe Redirection URL: https://mailbluster.com/unsubscribed.php?email=%e

Here the Lead email address is passed by using the query parameter email=%e

So, when the user clicks Unsubscribe as shown here:

Click on Unsubscribe to unsubscribe from the Mailing List

It will redirect to the page you have set earlier with the email address as shown below:

Email address is shown after redirecting to unsubscribe redirection URL

Why HTTPS protocol is not working for my Action URL?

Last update: March 18, 2024

The domain custom.mbmail1.com is hosted on an AWS EC2 server. Since it’s not routed through Cloudflare, its IP directly connects to an AWS server. This server has only two ports accessible: port 22 for SSH and port 80 for HTTP. Notably, it lacks port 443, which is essential for HTTPS connections. Consequently, the domain is unable to support the HTTPS protocol. This is a common reason why HTTPS protocol may not work for an Action URL hosted on such a server.

After I used my domain as the sender, my unsubscribe link isn’t working. It’s giving a “404: Page Not Found” error.

Last update: May 14, 2024

If you are seeing the error message: 404 Page not found after clicking the Unsubscribe link in your email campaign, then you need to set up Action URL in MailBluster.

The Action URL is used to set a domain for your subscribe, unsubscribe, and web version URLs. If you set the action URL, MailBluster will use it as the base URL for your subscribe, unsubscribe, and web version pages. Otherwise, MailBluster will use its default base URL.

You can set-up Action URL from Settings > Custom URL tab as shown in the screenshot below.

Setting up Action URL in MailBluster

You’ll also need to set up a CNAME record that directs to the MailBluster domain. Detailed instructions on this process are provided below:

Setting up Action URL DNS record

After setting up the Action URL and configuring your DNS record, you can test the behavior by sending test email to yourself.

If your DNS is not managed by Cloudflare, ensure that your Action URL uses the HTTP protocol.

Note that the Action URL set in MailBluster should update the web version URL, Unsubscribe URL in your email campaigns.

If you leave the Action URL blank, MailBluster will use its default base URL for your subscribe, unsubscribe, and web version pages.

What to do if my Domain Verification Status fails in MailBluster?

Last update: March 14, 2024

If the Domain Verification Status fails, then setting up DNS record after that will have no impact because Amazon SES does not check the records. You need to delete the domain from @‌Senders and then add the domain again, then it will retry.

Deleting the domain whose domain verification status is showing Failed

After deleting the sender domain, add the sender domain again by following this guide:
