E-mail templates can have the most varied models and concepts, each one of them with a different function. In the above section "Advertising aspects", we have already mentioned the uses and functions of each one of the most frequent formats.

Choosing the appropriate format is fundamental for an e-mail template to be effective. A different format must be used for each different function; for example, it would be wrong that a company use the format Newsletter to make monthly announcements and also to offer products as in a catalogue.

As a matter of fact, to use the same format for different functions will only confuse clients, who will not know what e-mails are about, or will eliminate unchecked e-mails by mistake. Nevertheless, it is also true that not all formats are so inflexible.

Whereas Newsletter is a format which should not be used for different functions -although the same design can be used repeatedly just by altering the contents-, a format such as personalized letter( including a picture of the sender) is appropriate for different clients and colleagues, and for different answers.

But even when the contents can be modified in all e-mail template formats, all formats, with the exception of personalized letter, would turn out to be boring and repetitive unless their designs were modified as time goes by.

Now, we will introduce you to the different e-mail template formats so that you can start thinking which one(s) might be better for your company.

 Newsletter

This format is used to inform the public about the latest news of a company concerning formal working aspects.

 Flyer

This format is used to advertise a product or service offered by a company. It is more suitable for selling than the above-mentioned Newsletter.

 Personalized letter including a picture of the sender

This format is used to communicate with clients or colleagues personally. It produces a strong sense of personalization.

 Catalogue

This format is used to introduce a series of products or services that a company is about to launch on the market.

 Price List

This format is used to make prices known to potential clients. It is particularly used by businesses or companies whose main activity requires that the public should have easy access to this information. E-mail templates are perfect for price lists because they are elegant in addition to be easy-to-store, and they suggest an instant reply.

 Invitations

This format is used to send invitations through e-mail. It is a formal, elegant format which will transmit a sense of personalization and will give prestige to the company sending the e-mail. A printable format so that the invitation can be shown at the entrance to the occasion is also possible.
