Marketing automation is like having a virtual assistant that manages campaigns, sends emails, posts on social media, and analyzes data without you having to do it manually. It is based on the use of software to improve the efficiency and personalization of marketing strategies. Tools like HubSpot, Marketo, or ActiveCampaign allow for audience segmentation, scheduled sending, and tracking of user behavior. This not only saves time but also improves lead-to-customer conversion, ensuring that each user receives the right message at the right time.
