We have found that Polaris sends Almost Overdue notices by email if the patron has a valid email address on their account, even if the patron has chosen TXT as their notification option. The only way to send an Almost Overdue text message is by checking the "Additional TXT notice" box. Most patrons who select TXT as their notification option do so because they do not read their emails, so the Almost Overdue alerts are ignored and late fines are incurred.

If a patron selects TXT as their notification option, the Almost Overdue & Autorenew notices should be sent by Vega Interact through SMS by default and not through email.
