Hooks and actions

wp_mail_catcher_mail_success is triggered when a message is sent and logged successfully. It has a single argument that is an array containing the log
id related to the id in the mail_catcher_logs MySQL table
time relative, readable time to when the log was saved
email_to the email address(es) that the message was sent to
subject the subject line of the message
message the contents of the message
status an integer depicting if the message was sent successfully or not (1 = sent successfully. 0 = sending failed)
error the error that occurred - if any
backtrace_segment a json_encoded object that shows which file and line the mail was initially triggered from
attachments a list of any attachments that were sent along with the email
additional_headers a list of any headers that were sent
attachment_file_paths a list of the location of any attachments that were sent
timestamp a unix timestamp of when the email was sent
is_html a boolean, that will be true if the message is a html email and false if not
email_from the from value of the email
wp_mail_catcher_mail_failed is triggered when a message failed to send and logged successfully. It has a single argument that is an array containing the log (same as the arguments for wp_mail_catcher_mail_success)
wp_mail_catcher_deletion_intervals is a filter that should return an array where each key is an amount of time in seconds, and the value is the label. Used to determine when a message has expired and should be deleted
wp_mail_catcher_before_success_log_save is a filter that is called just before a successful log is saved. It has a single argument that is the transformed log that will be saved - use this to alter the log before it's saved. Returning false will stop the log from being saved. Also note that this is fired even when an email has errored, because all logs are initially saved as "successful" before being possibly updated with an error (if applicable). This is because of the way the wp_mail and wp_mail_failed are implemented in WordPress.
time a unix timestamp of when the email was sent
email_to the email address(es) that the message was sent to
subject the subject line of the message
message the contents of the message
backtrace_segment an array that shows which file and line the mail was initially triggered from
wp_mail_catcher_before_error_log_save
time a unix timestamp of when the email was sent
email_to the email address(es) that the message was sent to
subject the subject line of the message
message the contents of the message
backtrace_segment an array that shows which file and line the mail was initially triggered from
error the error that occurred
wp_mail_catcher_redact is a filter that is called on the subject and message of a log, both before it's saved and before it's displayed - use this to remove sensitive content (e.g. tokens or links) from the logs. It has two arguments, the content being redacted and the name of the field (subject or message), and should return the redacted content. By default URLs containing action=rp or key= (such as password reset links) are replaced with [redacted], this can be turned off in the settings screen. Note that resending a log sends the redacted content
