General Questions
- Does Certain use a 3rd party email service for sending email?
- Yes.
- Certain uses SendGrid.com.
- Email is sent via SMTP.

Email Analytics Event Dashboard & Tabular View
- How often is the Email Analytics dashboard refreshed?
- The dashboard is refreshed every 10 minutes.
- What time zone are the time stamps in the dashboard reflected in?
- The Pacific Time zone is consistent with other timestamps in the Certain platform.
- When I move my event from ‘Testing’ to ‘Live’ status will the dashboard totals be cleared out?
- No.
- Totals reflect emails sent to both test and live registrations in the event as well as any deleted emails.
- As a best practice, include ‘Test’ in the name of any mass action emails so they can be excluded via filters on the dashboard.
- What do each of the email statuses mean?
- Sent — the message has been prepared and processed for delivery.
- Delivered — the recipient's email server has accepted the message.
- % delivered — the percentage of delivered emails equals delivered divided by sent.
- Total Opens — the total number of times the email was opened by recipients.
- One recipient may open the same email multiple times.
- % opened — the percentage of emails opened equals total opens divided by delivered.
- Unique Opens — the total number of recipients who opened the email.
- Total Clicks — the total number of clicks, including multiple clicks by the same recipient.
- Unique Clicks — the count of recipients who clicked on at least one link.
- % Not Opened — the total number of unread emails divided by the total emails delivered.
- Undeliverable — the number of emails that were undeliverable.
- The reason could be bounces (recipient's server rejected the message), dropped emails (no longer processed), spam, etc.
- % Other — the total number of undeliverable emails divided by the number of emails sent.
Registration Email Activity Summary Totals and Timeline
- How often is the Email Activity list and timeline updated within a registration?
- Unlike the dashboard, the list and timeline within a registration are updated in near real-time.
- Email Opens
- What is the difference between Total Opened and Unique Opens?
- Total Opened is the total number of times the email was opened.
- Unique Opens is the total number of recipients who opened the email.
- How are opens tracked?
- An invisible, one-pixel image is added at the end of each email.
- If the email recipient has images enabled and requests to SendGrid’s server for the image, an open event is logged.
- Open tracking is not recorded for text-only emails.
- Is there anything else I need to know about open tracking?
- Due to internet routing and other factors, some opens can be recorded multiple times within 0–30 seconds.
- When multiple opens of the same link are recorded within 30 seconds, only a single open is displayed in the registration timeline.
Click-Through Tracking
- Are link click-throughs tracked?
- Yes.
- This feature can be enabled at the portal // sub-account // event level.
- How do I enable click-through tracking on my portal and sub-accounts?
- It is enabled by default on all portals and sub-accounts and can only be enabled or disabled by Certain.
- For assistance, contact helpdesk@certain.com.
- How do I enable click-through tracking on my event?
- Navigate to Plan > Configure > Options > Functional Areas Needed by This Event > Event Module.
- Select “Email Click-Through Tracking.”
- If you do not see this option, it is not enabled for your sub-account or portal.
- For more information, contact help@certain.com.
- How does click-through tracking work?
- SendGrid is used to send emails.
- Click-through tracking overwrites links with a SendGrid domain visible only when the recipient hovers over the link.
- Upon click, the browser opens the original website while the displayed URL may differ.
- Will recipients be concerned about the overwritten link and think it is a phishing email?
- This is a valid concern; however, this URL overwriting is typical of email tracking.
- Documentation on tracking is available at SendGrid’s tracking guidance.
- Can the domain displayed in the overwritten links match that of my portal?
- Yes, this is possible but requires coordination with your DNS manager and best practices with branding the links.
- Where can I see the link that a registrant clicked on?
- Drill into a registration and navigate to the Email Activity timeline to see the clicked link with a timestamp.
- What if a recipient clicks on multiple links in the same email?
- Each click is tracked and recorded in the timeline.
- Is there anything else I need to know about click-through tracking?
- Some clicks can be recorded multiple times within seconds; if so, only a single click is displayed within 30 seconds of another.
- Should I have any privacy concerns regarding enabling click-through tracking in my emails?
- As a best practice, include your organization’s privacy policy in registrations.
- Consider mentioning third-party technologies used to analyze trends and track user movements in emails.
