In some circumstances, email messages sent from Cab Grid (WordPress) can not get through. There are a number of reasons for this. This article attempts to address some common email deliverability issues.
Check Message Are Sent
Check general email messages are being sent by implementing a simple contact form and sending a test message. See https://cabgrid.com/help-and-support/troubleshooting/error-email-sending-problem/
Different providers (Gmail, Hotmail, iCloud, Yahoo, etc.) apply different filtering rules. Try sending test messages from the system to different email addresses on different domains to see if only one provider is blocking messages.
Enable Cab Grid Pro logging
Cab Grid Pro specific logging can be enabled by editing the _settings.php file:
Complete some test bookings, then analyse the log file…
The log file can be downloaded via FTP or read using the WordPress plugin editor (if enabled): WordPress Admin > Plugins > Editor > Cab Grid Pro > log.txt
Check Server Error Logs
Most web servers also maintain an error log. This details wider system issues. Some hosting providers do not enable server logs by default. Contact your provider for info.
Server logs are usually stored in a directory above the website files directory. They can be downloaded via FTP or accessed using a hosting control panel. Contact your provider for more info.
Cab Grid Pro attempts to follow industry standard guidelines to insure email deliverability. However, since Cab Grid Pro offers complete email customisation, there are some further considerations that may effect email deliverability:
The sending address can impact email deliverability. Try changing the admin email address under WordPress Admin > Settings General > Email address.
Use 3rd-Party email services
Once installed and configured, all WordPress email including Cab Grid notifications will be sent via Send Grid. Send Grid will format messages for best deliverability, and provide stats. They offer a free level of service and charge depending on the volume of mail sent.
Use SMS Text Notifications
If email deliverability is inconsistent, consider sending notifications (to both admin and customer) via SMS text message. Cab Grid Pro v5 integrates Twilio to provide SMS functionality.
