The marketing team at Ursa Major Solar wants to send a personalized email whenever a lead fills out the web-to-Lead form on their website. They want…

Auto response rules are a way to automatically send email responses to leads or cases based on

certain criteria such as lead source, industry, etc. They can be used to send personalized emails

whenever a lead fills out a web-to-lead form on a website and send different messages based on the

lead industry field value. Using validation rule to trigger workflow to email the lead is not possible

because validation rules cannot trigger workflows or send emails; they only prevent records from

being saved if they do not meet certain criteria. Adding a public group and process builder to email

the lead is unnecessary because auto response rules can handle this requirement without additional

configuration or customization. Creating an assignment rule to email the lead is also unnecessary

because assignment rules are used to assign leads or cases to users or queues based on certain

criteria, not send emails; although they can have email alerts as part of their actions, they are not as

flexible as auto response rules for personalizing email messages. Reference:
