Abstract

Systems and methods associated with subscription-based electronic messaging are described. A method includes obtaining registration information associated with a user who has subscribed to receive electronic messages from a subscription-based messaging service. The registration information includes an electronic address of the user and a private token that is known to the user and to the subscription-based messaging service. The method includes embedding the private token in an electronic message associated with the subscription-based messaging service, and such inclusion of the private token may indicate to the user that the electronic message is from a legitimate sender associated with the subscription-based messaging service. The method also includes sending the electronic message to the electronic address of the user.

Claims

1. A method comprising:

registering a user with a subscription-based messaging service, the registering including;

obtaining, at a computing system, registration information associated with a user who has subscribed to receive electronic messages from the subscription-based messaging service, the registration information including an electronic address of the user and a private token that is known to the user and to the subscription-based messaging service, the private token being selected by the user; and

analyzing, at the computing system, the private token to determine whether the private token is likely to occur in electronic messages from the subscription-based messaging service, and in response to determining that the private token is likely to occur, notifying the user;

embedding, using the computing system, the private token in an electronic message associated with the subscription-based messaging service, wherein inclusion of the private token in the electronic message indicates to the user that the electronic message is from a legitimate sender that is associated with the subscription-based messaging service; and

sending, using the computing system, the electronic message to the electronic address of the user.

2. The method of claim 1, wherein the private token is embedded in the electronic message such that the private token is visible to the user within a body portion or a subject portion of the electronic message.

3. The method of claim 1, wherein the private token is embedded in the electronic message such that the private token is not visible to the user in a body portion or a subject portion of the electronic message.

4. The method of claim 1, wherein the private token includes a textual word, an image, or a combination of a textual word and an image.

5. The method of claim 1, wherein the private token is generated by the subscription-based messaging service and communicated to the user during registration with the subscription-based messaging service.

6. A subscription-based messaging system comprising:

one or more processors;

a registration engine that executes on at least one of the one or more processors to obtain registration information associated with a user who has subscribed to receive electronic messages from the subscription-based messaging system, the registration information including an electronic address of the user and a private token that is known to the user and to the subscription-based messaging system, the registration engine analyzing the private token to determine whether the private token is likely to occur in electronic messages from the subscription-based messaging system, and in response to determining that the private token is likely to occur, notifying the user during registration; and

a messaging engine that executes on at least one of the one or more processors to generate an electronic message addressed to the electronic address of the user, the electronic message including the private token.

7. The subscription-based messaging system of claim 6, wherein inclusion of the private token in the electronic message indicates visually to the user that the, electronic message is from a legitimate sender associated with the subscription-based messaging system.

8. The subscription-based messaging system of claim 6, wherein analyzing the private token comprises comparing the private token to an index of terms associated with messages from the subscription-based messaging system.

9. The subscription-based messaging system of claim 6, wherein analyzing the private token comprises comparing the private token to terms included in prior electronic messages sent from the subscription-based messaging system.

10. The subscription-based messaging system of claim 6, wherein the private token is embedded in the electronic message such that the private token is visible to the user within a body portion or a subject portion of the electronic message.

11. The subscription-based messaging system of claim 6, wherein the private token is embedded in the electronic message such that the private token is not visible to the user in a body portion or a subject portion of the electronic message.

12. The subscription-based messaging system of claim 6, wherein the private token includes a textual word, an image, or a combination of a textual word and an image.

14. The subscription-based messaging system of claim 6, wherein the registration engine obtains the private token from the user during registration with the subscription-based messaging service.

13. A non-transitory computer-readable storage medium storing instructions that, when executed by one or more processors, cause the one or more processors to:

register a user who has subscribed to receive electronic messages from a subscription-based messaging service, by obtaining registration information associated with the user, the registration information including an electronic address of the user and a private token that is selected by the user;

analyze the private token to determine whether the private token is likely to occur in electronic messages from the subscription-based messaging system, and in response to determining that the private token is likely to occur, notify the user during the registration of the user with the subscription-based messaging service;

generate an electronic message associated with the subscription-based messaging service, the electronic message including the private token; and

send the electronic message to the electronic address of the user.
