Some email clients/services (e.g. Outlook/Exchange) disable showing images that need to load from external URLs as they do in our result emails. To resolve this, you can add help@andfrankly.com or the entire @andfrankly.com domain to the “Safe Sender” list (note that this might be a different setting than Whitelisting.) Depending on your email settings, you may also need to allow downloading images in emails.
Adding us to the “Safe Sender” list can be done by each individual user if allowed by the customer’s settings, or the customer may need to add us to “Safe Sender” globally through a Group Policy (GPO) so that it applies to all users in the organization.
