What is the Vetter Carrier Pigeon?
The Vetter Carrier Pigeon is the system we created in order to test on your behalf whether your emails are spammed (known to some in the marketing world as "Inbox Placement").
Our Carrier Pigeon is built using Vetter’s domain infrastructure, its network of multiple inboxes, and Amazon Simple Email Service (SES). Amazon SES is a cloud-based service that allows you to send vast amounts of email for a very reasonable price. It is mainly used by marketers and application developers.
Why does using my own email service work better?
When sending an email, your email address is one of the most important factors spam filters use for determining whether the email will be categorized as spam or whether it will successfully reach the inbox. Because of this, using your own email service will significantly increase the accuracy of our test results, vis-a-vis using Vetter's Carrier Pigeon's default service.
What email services does Vetter support?
We are always adding new domain infrastructure systems to Vetter. However, to date we already support:
- Amazon SES
What do you mean by an “app password”?
If you have 2-factor authentication enabled for your Gmail account or any Microsoft account (Hotmail, Outlook, Live, etc.), Vetter will not be able to access your email account - even if you do provide your password. To resolve this, you will have to log into your email account and create an 'app password'. This is a code generated specially for third party service provides such as Vetter. This code will allow Vetter to connect to your account securely. Note that the app password generated is not your email access password. You can revoke it at any time, without affecting your email account's password or security.
Security and safety
What does Vetter do with my email service credentials and is it secure?
Vetter uses your email service credentials to connect to the email service you want Vetter to use. This means that Vetter takes your email service credentials to authenticate itself with your email service. Once authenticated, your email service grants Vetter the permission to send emails using your email address. Gmail and Microsoft based email services also grant Vetter the permission to access email service inboxes. This permission cannot be changed by us (or anyone really). Nevertheless, we do not access email service inboxes under any circumstances.
With the permission to send emails using your email address granted, each time you vet an email Vetter sends different emails to our network of test email accounts. We limit the number of emails sent to: 10 Gmail accounts, 10 Yahoo accounts, and 10 Outlook/Live/Hotmail accounts.
Vetter disconnects from your email service immediately after these emails have been sent.
Whenever you check the option to "save your email service details for future use", Vetter takes multiple steps to ensure that your credentials are kept safe including - but not limited to:
- storing your credentials in databases running on independent servers;
- keeping these servers up to date (security-wise); and protecting them by a firewall; and
- storing your credentials in a strong encrypted format (AES-256).
If you have more questions on how we keep your credentials safe, write to us at: firstname.lastname@example.org
IMPORTANT: if your email service charges you for sending emails (e.g., Postmark, SendGrid, etc.), you will incur the cost of sending 30 emails from that service. Usually, this is a nominal fee, but please be aware of this cost.
Does Vetter read the emails that I send?
Vetter DOES NOT read the emails that you send.
Emails sent via the Vetter interface are only accessible by you. We use automated scripts to detect if those emails reach our test accounts, and whether they end up in the inbox or spam. Once these emails are detected, they are deleted from the test accounts permanently. No human eyes see your emails ever.
IMPORTANT: WE DO NOT ENCOURAGE SPAMMING ACTIVITIES. If our algorithms flag your account for repeatedly testing emails that appear to be spam, we may lock your account and ban you from using our service. In such a scenario, you may request permission for us to audit the emails you have sent in order to determine if they are spam or not.
Do you sell my data?
Vetter DOES NOT sell your data.
Our business model is simple and direct: you, the customer, pay us directly via a monthly subscription to use Vetter. We have the utmost respect for your privacy and confidentiality. In particular, we do not sell or share your individual or aggregate data with third parties.
