Since version 1.0, Direct Mail has always employed encryption to keep the contents of your email campaigns, mailing lists, reports, etc. private as they move between our servers and your Mac. This is also true for our iOS companion app, Stamps. Not only does this keep your information private, but also ensures that your data is not tampered with as it is transferred across the Internet. Beginning recently, we have started encrypting the content of your email campaigns as they are sent to each person on your list, too. This is known as encryption in transit, and it uses the same technology (TLS) that your web browser uses to keep your Internet browsing safe from hackers. This protection is enabled for all customers who send their email via e3 Delivery Service.
You may wonder why Direct Mail did not encrypt email in transit right from version 1.0. The reason is that most email providers (like AOL, Yahoo, Hotmail, etc.) did not support the necessary technology until only recently. As the need for encryption and digital privacy has become more apparent, a large number of email providers have made the necessary changes to accept email over secure channels.
Despite these advances in email security, it’s important to remember that it is still not a good idea to send sensitive information like credit card numbers, social security numbers, passwords, etc. via email. As mentioned above, a large number of email providers support encryption in transit, but there are still some who do not. There may be subscribers on your mailing list whose email providers do not yet allow them to receive their email securely.
