Most people couldn’t imagine a life without e-mails. Whether you use them to communicate for business or personal reasons, e-mails have practically replaced traditional letters. Over 200 billion e-mails are sent around the world each day and despite the rise in social media and instant messaging, they show no sign of slowing down. Our E-mail Guide forms part of the IONOS Digital Guide and is dedicated to the basic framework of the e-mail–from the technical security requirements to marketing strategies you should use when sending business e-mails. The contents of this E-mail Guide cater for both beginners as well as more experienced computer users.

The E-mail Guide’s target audience

The numerous e-mail tips in the guide are aimed at a wide readership, from hobbyists and novices to IT and e-mail marketing professionals. Owners of small and medium-sized companies can also benefit from articles that provide information on how to create business e-mails and build successful e-mail marketing campaigns. The e-mail guide takes into consideration that readers have different levels of IT knowledge; as well as introductory articles on FAQs (e.g. ‘How is an e-mail sent?’ or ‘What should an e-mail header contain?’) there are also more detailed and specific articles such as ‘E-mail encryption with PGP’ or ‘Creating individual newsletter templates’.
