Testing via Proxy Email Address
If you’re operating your own mail server or email account with a delivery vendor like Amazon SES, SendGrid or other you can use this option. It is simple as 1, 2, 3.
- Enter your SMTP settings in GlockApps.
- Select spam filters and mailbox providers for testing.
- Send your email to the proxy email address.
GlockApps will automatically re-send the message to the seed email addresses at mailbox providers you chose.
This option eliminates the need for you to copy-paste the entire seed list and test id to your email software. You only need to send your message to the single proxy email address. And our system will do the rest.
You can create multiple email accounts in the GlockApps email spam checker tool using different SMTP settings and send tests via each account.
Here are the steps to follow:
1. Enter SMTP Settings.
Go to Inbox Insight -> Sending Accounts in your GlockApps dashboard.
Click Create Sending Account.
Enter your sender information and the SMTP server information.
Sending account name – can be any name for your account. It will be visible in GlockApps only.
From email – the email address your emails will be sent to the seed list from.
SMTP server – the name of the SMTP server. For example: smtp.gmail.com for a Gmail account or smtp-relay.gmail.com for a Google Workspace account.
Port – SMTP port number (465 or 587).
SMTP username – login for your account with the SMTP server. As a rule, it’s the full From email address.
SMTP password – password for your account with the SMTP server. If your SMTP user doesn’t require authentication, type nopassword in the Password field. The username can be any or empty. With nopassword, the username is ignored.
Some mailbox providers such as Gmail, Outlook, and Office 365 require an App password to be created and used in third party applications.

By default, the test is saved to the root Home folder. In the menu, you can select a different folder to save the test to. Folders allow easy sort tests for your convenience.
Enable or Disable Link Checker
To ensure the validity of each URL (excluding the unsubscribe link) in your message, GlockApps conducts a thorough check. It even goes the extra mile to extract target URLs if you use redirects and scrutinizes the domain in the target URL against domain blacklists, which include Spamhaus DBL Domain Block List, involvement DNSBL, and SURBL multi (Combined SURBL list).
Additionally, GlockApps may follow the unsubscribe link if you use a very specific anchor text and unsubscribe a seed email address on your list. To prevent this, disable the link checker.
While sending your message to the seed list GlockApps keeps only ‘MIME-Version’, ‘Content-Type’, ‘Reply-To’, ‘List-Id’, ‘List-Unsubscribe’ and ‘Subject’ message headers.
If you want to keep your custom message headers, for example, to tell SparkPost which dedicated IP to use for email sending, specify them in the Keep email headers field.
To add a custom header during the test, enter the header field name and value.
2. Select Mailbox Providers.
Choose the spam filters and mailbox providers for the test. You can select/unselect them individually or in blocks.
To finish, click Check & Create.
If your SMTP settings are correct, the sending account will be saved. If something goes wrong, you’ll see an error message. It’s recommended to read it and fix the SMTP settings in GlockApps or the settings in your account with the SMTP server.
3. Send the Message to the Proxy Email Address.
Copy the proxy email address and send the message to it.
When the message is received by the proxy email address, our system re-sends it to the chosen seed list via your SMTP settings. The test will be created in the chosen folder. You can go to the folder, click on the test, and view the deliverability report.
- You can use the same proxy email address as many times as you need. Each message sent to the proxy email address will create a new test in GlockApps. With time, proxy email addresses may be spread over different mailing lists and may be abused by malicious senders. To avoid this, you can use the Regenerate option to create a new proxy email address for the sending account.
- If your SMTP server only accepts the connections from allowed IP addresses, add the GlockApps IP address 188.8.131.52 to your allowed senders list or whitelist.
Each ISP or mailbox provider stores information about the sender and outgoing mail servers used to send large volumes of emails to it. They track how the recipients engage with the received emails and over time each sender gains a reputation, good or otherwise. ISPs update their filtering algorithm on a regular basis depending on how they treat the sender at this time. In your GlockApps dashboard, you can see your current sender reputation and know if any of ISPs such as Gmail, or popular filters are flagging your email as spam.
