Essential advantages of having a consistent email header and footer

• The email header provides readers with the option to view your email in the browser. In case any issues occur with your email while in the inbox, your recipients can click on the "view in browser" link to view it in the browser. Email clients have different limitations when rending your email, however browsers have very little limitations so when viewing your email in the browser it should always display correctly. 
• It shows the reader who the email was sent to and who it was sent from. This is a great benefit as it allows the reader to recognise your brand as soon as they see your email.
• It advises readers to add your email address as a contact within their address book to ensure your email is received into the inbox. This will help to ensure your email will not land within their junk mail which can prevent it from being read.

• Displaying a powered by logo and the messages to state who it was sent to and who it was sent from is a good benefit as both of these will allow your recipient to recognise and remember your brand.
• Displaying “Subscribe and Forward” links is a great idea as this allows your readers to forward and share your email giving it a wider audience. As it will be sent to readers that have not subscribed, having the "subscribe" link allows those users to signup so they receive all future mailings.
• Including social sharing options will allow your recipients to share it on their own Facebook, Twitter and more. This will help your email to reach a wider audience and it can also help to grow your social networks.

• Both, our email header and footer, gives your readers the option to "unsubscribe" from emails they no longer wish to receive. This can help you in future campaigns as it will prevent complaints being made against your brand that could potentially affect your reputation. It will also ensure you are only sending to opt-in users that look forward to your emails which will increase delivery and action taken within your emails.
