Domain spoofing, phishing and spear phishing are now the order of the day, forcing more and more companies to equip themselves with email authentication systems in order to secure the best delivery rates, maintain a high reputation and get through spam filters.
How to design your forms safely? The Contactlab platform already offer the possibility of using a captcha to control subscriptions, for example to your newsletters, from illegitimate activities. The feature is always active and available when creating a form on the platform.
