Requests
The number of requests sent to the email server to send an email.
Delivered
A delivery is recorded when a request to send an email results in the email being accepted by the receiving server.
However, this does not necessarily mean that the message reached the recipient’s inbox.
Some users and some email applications may filter the email away from the inbox even though the email was delivered to (read: accepted by) the recipient email server (e.g. spam filter or inbox rules).
If an email is indicated as delivered you can be certain that it was not deferred by the ISP.
Opens
The total number of times your recipients opened your emails.
SendGrid inserts a small, transparent image into all emails that will be tracked. When a customer reads an email, their client application loads the tracking image which registers the open event with SendGrid.
Not all email clients load images by default. Microsoft’s Outlook, Apple’s Mail.app, Mozilla’s Thunderbird, and Google’s Gmail do not load images.
As such, there may be many occasions where recipients will have received a message, opened it, and it will never be counted as opened because there is no way to track the event.
Unique Opens
The number of unique individuals that have opened your emails.
Clicks
The “Clicks” percentage is the total number of times your users have clicked on the various links within your emails, divided by the total number of Delivered messages.
The “Unique clicks” percentage is the number of unique individuals that have clicked the links in your emails, divided by the total number of Delivered messages.
This statistic requires that the Click Tracking feature be enabled under your Tracking Settings. Users clicking a SendGrid Unsubscribe link will not count as a Click.
However, if you use a third-party unsubscribe link, it will be tracked as a Click.
Unique Clicks
The number of unique individuals that clicked a link in your emails
Unsubscribes
Not used as eshots have their own brand/website based subscription management.
Bounces
A bounce occurs when a sent message is rejected by the receiving mail server.
The most common causes for bounced email messages include a misspelled or non-existent email address.
Repeat bounces are added to the suppression list to avoid impacting sender reputation.
Blocks
Blocks happen when your message was rejected for a reason related to the message, not the recipient address.
This can happen when your mail server IP address has been added to a blacklist, blocked by an ISP, or if the message content is flagged by a filter on the receiving server.
Repeat blocks are added to the suppression list.
Bounce Drops
Messages are dropped when the recipient email address is listed on the suppression list (due to repeat bounce or block, see above).
