and at least one processor to execute the instructions to: receive a piece of electronic correspondence from a sender computing device; determine that the piece of electronic correspondence is sent to a recipient that requests that the piece of electronic correspondence has an electronic stamp; send a request to attach the electronic stamp to the piece of electronic correspondence to the sender computing device; receive the piece of electronic correspondence with the electronic stamp and forward the piece of electronic correspondence to the recipient; receive one of an acknowledgement and a rejection of the piece of electronic correspondence from the recipient; and return the electronic stamp to the recipient after the acknowledgement to allow the electronic stamp to be reused in a future piece of electronic correspondence. ### Claim 2 (depends on 1) The system of claim 1, the at least one processor further to receive a request for at least one electronic stamp, send a request for a monetary value for the at least one electronic stamp, issue the at least one electronic stamp, and send the at least one electronic stamp to the sender computing device. ### Claim 3 (depends on 1) The system of claim 1, wherein the electronic stamp has a monetary value. ### Claim 4 (depends on 1) The system of claim 1, wherein the electronic stamp comprises cryptocurrency having a monetary value. ### Claim 5 (depends on 1) The system of claim 1, wherein the electronic stamp comprises a token having a monetary value. ### Claim 6 (depends on 1) The system of claim 1, the at least one processor further to receive the rejection of the piece of correspondence and send a notification of the rejection to the sender computing device. ### Claim 7 (depends on 6) The system of claim 6, the at least one processor further to receive the electronic stamp associated with the rejection, generate a monetary value that is less than an original monetary value for the electronic stamp, and send the monetary value that is less than original monetary value for the electronic stamp to the sender computing device. ### Claim 8 (depends on 1) The system of claim 1, wherein a server computing device associated with the recipient sends one of the acknowledgement and the rejection after a period of time. ### Claim 9 (depends on 1) The system of claim 1, wherein the request to attach the electronic stamp indicates a requested monetary value of the electronic stamp and an acceptable electronic stamp format. ### Claim 10 (depends on 1) The system of claim 1, wherein the electronic correspondence comprises one of an email message, a text message, a social media message, a voice message, a data message, and a file. ### Claim 11 A method, comprising: receiving, by at least one processor, a piece of electronic correspondence from a sender computing device; determining, by the at least one processor, that the piece of electronic correspondence is sent to a recipient that requests that the piece of electronic correspondence has an electronic stamp; sending, by the at least one processor, a request to attach the electronic stamp to the piece of electronic correspondence to the sender computing device; receiving, by the at least one processor, the piece of electronic correspondence with the electronic stamp and forwarding the piece of electronic correspondence to the recipient; receiving, by the at least one processor, one of an acknowledgement and a rejection of the piece of electronic correspondence from the recipient; and returning, by the at least one processor, the electronic stamp to the recipient after the acknowledgement to allow the electronic stamp to be reused in a future piece of electronic correspondence. ### Claim 12 (depends on 11) The method of claim 11, further comprising receiving a request for at least one electronic stamp, sending a request for a monetary value for the at least one electronic stamp, issuing the at least one electronic stamp, and sending the at least one electronic stamp to the sender computing device. ### Claim 13 (depends on 11) The method of claim 11, wherein the electronic stamp has a monetary value. ### Claim 14 (depends on 11) The method of claim 11, wherein the electronic stamp comprises cryptocurrency having a monetary value. ### Claim 15 (depends on 11) The method of claim 11, wherein the electronic stamp comprises a token having a monetary value. ### Claim 16 (depends on 11) The method of claim 11, further comprising receiving the rejection of the piece of correspondence and sending a notification of the rejection to the sender computing device. ### Claim 17 (depends on 16) The method of claim 16, further comprising receiving the electronic stamp associated with the rejection, generating a monetary value that is less than an original monetary value for the electronic stamp, and sending the monetary value that is less than original monetary value for the electronic stamp to the sender computing device. ### Claim 18 (depends on 11) The method of claim 11, wherein a server computing device associated with the recipient sends one of the acknowledgement and the rejection after a period of time. ### Claim 19 (depends on 11) The method of claim 11, wherein the request to attach the electronic stamp indicates a requested monetary value of the electronic stamp and an acceptable electronic stamp format. ### Claim 20 (depends on 11) The method of claim 11, wherein the electronic correspondence comprises one of an email message, a text message, a social media message, a voice message, a data message, and a file. ### Claim 21 A non-transitory computer-readable storage medium, having instructions stored thereon that, when executed by at least one processor cause the at least one processor to perform operations, the operations comprising: receiving a piece of electronic correspondence from a sender computing device; determining that the piece of electronic correspondence is sent to a recipient that requests that the piece of electronic correspondence has an electronic stamp; sending a request to attach the electronic stamp to the piece of electronic correspondence to the sender computing device; receiving the piece of electronic correspondence with the electronic stamp and forwarding the piece of electronic correspondence to the recipient; receiving one of an acknowledgement and a rejection of the piece of electronic correspondence from the recipient;
