Methods and systems for providing information relating to an event
An organizer may send information relating to an event to participants via text messaging without having participants' texting numbers. Particularly, organizer may be associated with a texting number. Organizer sets event's start/end times, and provides email addresses for event invitees. Email requests invitees' texting numbers to participate in event. Texting numbers are stored, and encrypted respectively as identifiers. Organizer's message for participants is sent as text message to participants' texting numbers between event's start/end, and may be sent as if the message originated from organizer's texting number. When event ends, participants' texting numbers are deleted unless a participant participates in organizer's later ending event. In response to invitation to organizer's later event, a received participant's texting number may be encrypted as later identifier, and compared with identifier from earlier event. If a match, organizer's text message sent to participant during prior event is included in organizer's or participant's conversational history.
1. A method for preventing transmission of unwanted electronic communication to an anonymous recipient when providing an electronic correspondence history for the anonymous recipient, the method comprising:
receiving, by an online communication service and from a computing device associated with an organizer, a first request to send a first electronic invitation to an invitee on behalf of the organizer;
transmitting, by an online communication service and responsive to the first request, the first electronic invitation to a computing device associated with the invitee, wherein the first electronic invitation identifies a first event having an end time and is transmitted on behalf of the organizer;

generating a first identifier for the invitee by encrypting the obtained address;
preventing the online communication service from accessing the obtained address subsequent to the end time of the first event;
performing, by the online communication service and based on receiving a second request to send a second electronic invitation to the invitee, operations comprising:
matching the first identifier to a second identifier that is generated from a second electronic response,
generating, based on the matching, an electronic communication including (i) information describing a second event specified in the second request and (ii) historical correspondence regarding the first event that was transmitted on behalf of the organizer, and

wherein the method further comprises transmitting, from the online communication service to the short message service address, messages with information about the first event,
wherein the historical correspondence comprises the transmitted messages.
6. The method of claim 1 , wherein the address is encrypted by applying an irreversible encryption to the address and the second identifier is generated by applying the irreversible encryption to an address obtained from the second electronic response.
7. The method of claim 6 , wherein the irreversible encryption comprises a one-way hash function.
8. The method of claim 6 , wherein preventing the online communication service from accessing the address comprises deleting the address from any non-transitory computer-readable medium controlled by the online communication service.
9. The method of claim 8 , further comprising, prior to deleting the address:
accessing, by the online communication service, data describing a plurality of end times for a plurality of events and identifying the invitee as a participant in each of the plurality of events; and
determining, by the online communication service, that each of the plurality of end times has elapsed, wherein the address is deleted based on determining that each end time for each event involving the invitee has elapsed.
10. A system comprising:
a processing device; and
a non-transitory computer-readable medium communicatively coupled to the processing device and storing instructions that provide an online communication service,
wherein the processing device is configured for executing the instructions and thereby performing operations comprising:
receiving, from a computing device associated with an organizer, a first request to send a first electronic invitation to an invitee on behalf of the organizer;
transmitting, responsive to the first request, the first electronic invitation to a computing device associated with the invitee, wherein the first electronic invitation identifies a first event having an end time and is transmitted on behalf of the organizer;
obtaining an address for communicating with the invitee over a data network or a telecommunication network, wherein the address is obtained from a first electronic response received subsequent to transmitting the first electronic invitation;
generating a first identifier for the invitee by encrypting the obtained address;
preventing the online communication service from accessing the obtained address subsequent to the end time of the first event;
based on receiving a second request to send a second electronic invitation to the invitee:
matching the first identifier to a second identifier that is generated from a second electronic response,
generating, based on matching the first identifier to the second identifier, an electronic communication including (i) information describing a second event specified in the second request and (ii) historical correspondence regarding the first event that was transmitted on behalf of the organizer, and
transmitting, on behalf of the organizer, the electronic communication to the address obtained from the second electronic response.
11. The system of claim 10 , wherein the address obtained from the first electronic response comprises at least one of a short message service address or an email address.
12. The system of claim 10 , wherein transmitting the first electronic invitation and the second electronic invitation on behalf of the organizer comprises identifying, in the first electronic invitation and the second electronic invitation, an additional address for the organizer as a source of the first electronic invitation and the second electronic invitation.
13. The system of claim 12 , wherein the first electronic invitation includes a uniform resource locator for a website and the first electronic response comprises data received from the invitee via an interface accessible at the website.
14. The system of claim 13 , wherein the address obtained from the first electronic response comprises a short message service address,
wherein the operations further comprise transmitting, to the short message service address, messages with information about the first event,
wherein the historical correspondence comprises the transmitted messages.
15. The system of claim 10 , wherein the address is encrypted by applying an irreversible encryption to the address and the second identifier is generated by applying the irreversible encryption to an address obtained from the second electronic response.
16. The system of claim 15 , wherein the irreversible encryption comprises a one-way hash function.
17. A non-transitory computer-readable medium storing instructions that are executable by a processing device and that provide an online communication service, the instructions comprising:
