Ability to link to previously sent emails

With our current email tool, we have the ability to provide a link to any email we've previously sent. An example: "In case you missed our last email, we've provided a link to it here: [link]". We work with large corporate clients who have extreme spam filters, and receive a large daily quantity of emails. Being able to link to these previously sent emails gives an opportunity to anyone who may have missed the email previously, or never received it.
