Several factors contribute to limited control in email marketing, including:
Email Service Providers (ESPs): Different ESPs have different algorithms and policies that can affect email deliverability. Spam Filters: Spam filters use complex algorithms to determine whether an email should be delivered to the inbox or spam folder. User Behavior: Recipients’ actions, such as marking emails as spam or not opening them, can influence the success of your campaigns. Technical Issues: Problems such as server downtime or incorrect email formatting can hinder email delivery. Legal Regulations: Compliance with laws like GDPR and CAN-SPAM can limit certain email marketing practices.
