Sending Glossary

Confused about any of the phrases used in Mailtrap? Chances are you’ll find your answer below.

Bounce - one of the possible events, also known as “hard bounce”. Most commonly, a bounce occurs when the recipient’s email address is incorrect or the server declines a message. It indicates a permanent failure of delivery. You won’t be able to send any further emails to this address from this domain.

Category - a method used to categorize different types of emails sent from your Mailtrap account. You specify a category when creating an email as one of its parameters. For each unique category specified this way, you’ll be able to see separate email analytics. Example categories can include password reset, invoice, welcome email, etc.

Click - an event that occurs when a link in your email is clicked. Click tracking must be enabled prior to sending an email for any clicks to be recorded. 

Note: when an email with click tracking enabled is forwarded, all further clicks will also be included in the click count.

Client Sending IP - IP address of a device that was used to send an email. 

Domain (or Sending Domain) - the domain used in the “from:” field of an email. You must be the owner of a domain and have it verified to be able to send emails from Mailtrap. No public domains can be used with Mailtrap Sending (e.g. Gmail, Hotmail).

Email Logs - the list of all the emails sent from your account. Contains all the vital details of each message, including the recipient’s details, timestamps, HTML/CSS of a message, opens/clicks stats, as well as additional tools, such as email preview or spam check.

Event - a particular action that occurred to your email. The available events are: Sending, Delivery, Reject, Open, Click, Bounce, Spam, Unsubscribe, Soft Bounce, Suspension. In the Email Logs, you can view all the events associated with a particular message in chronological order.

Mailbox Provider - an email service used by the end recipient to receive emails. Examples include Gmail, Outlook, Cisco email protection, or Mimecast email protection.

Mailtrap Sending IP - IP address of Mailtrap, used to send a message to the final recipient.

Open - an event that occurs when an email is opened. Mailtrap inserts an invisible pixel into an email. When a message is opened and a pixel is “displayed”, an ‘open’ event is recorded. 

Some mailbox providers, browsers, and plugins block the tracking of opens. Users or their providers can also block images from being displayed. In each of these cases, no “open” event will be recorded even if an email is opened. 

A message can be opened multiple times. When an email is forwarded, the tracking pixel won’t change, so any subsequent opens will count towards the opens count. Read more about how email tracking works.

Recipient IP - IP address of a device or an email server where an email was opened. If a message is opened on devices using different IP addresses, multiple Recipient IPs will be recorded. If a message is not opened at all, no Recipient IP will be displayed.

Spam - one of the possible events. This happens when a recipient chooses to report a message as spam. No further messages will be delivered to such recipients. Recurring spam complaints are known to very negatively influence email deliverability.

Status - indicates the most recent state of your message. The available statuses are: Delivered, Not Delivered, Enqueued, and Opted Out. An email can have only one status at a time.

Suppression list - a list of email addresses that Mailtrap won’t send any further emails to. Email addresses land on a suppression list when a message bounces, a recipient unsubscribes, or they report an email as spam. At this point, you won’t be able to see a suppression list for any of your domains.

Suppression lists are individual for each of your sending domains. If an address lands on such a list for domain X, it won’t prevent you from sending emails to them from other verified domains. If you, however, try to email them from domain X, an email will be declined with the reject event recorded on its account.

Transactional Email - the type of email triggered by a user’s action (e.g. registration, password reset, etc.) or a certain event in the system (monthly invoice, notification about a limit reached, etc.). Transactional emails are usually triggered separately for each recipient, as opposed to marketing or sales emails that are traditionally sent in batches.

Unsubscribe - one of the possible events. It occurs when a recipient of your email clicks on the “unsubscribe” link in your message. No further emails will be sent to this recipient from a given domain.
