<Introduction> I am looking for a developer who can build the Desktop Application by using “Electron”. [login to view URL] This application is for Simple Email Blasting Software, (similar to SendBlaster4) This is mainly used in Windows PC, but I hope Mac is also accepted. <Features> User can upload guest list (csv). List should contains first name, last name, company, job title, ID, email address, and some remarks column. User can see the uploaded guest list on the table User can create the email template by html, and save. User can edit/delete the email template. User can personalize the email text by using tags such as ; {Contact_firstname} {Contact_lastname} {Contact_organisation} {Contact_designation} {Contact_email} {Contact_countrycode} {Contact_mobile} {Contact_remarks} {Contact_remarks2} {Contact_remarks3} {Contact_accept_button_link} {Contact_decline_button_link} {Qrcode_img_link} {unsub} Those tags are automatically replaced with the actual data in the uploaded guest list. Every guest see the different information. User can configure the SMTP server information such as (Email address, Password, SMTP server URL, authentication required, SSL, Port, Sender Name, Reply-to Email, CC, BCC, etc.) User can do connection test after he/she enter the SMTP information. User can send the email to the uploaded guests by the configured SMTP instantly. User can set the following figure about the email blasting. * Pause between messages: the number of seconds elapsing between message sending. (default 1 second) * Pause between blocks: the number of messages elapsing between each block of messages. (default 5 second) * Messages per block: the number of messages sent in each block (default 50) * Timeout: the maximum number of seconds after which the message sending is aborted (default 60 second) * Connections: the maximum number of simultaneous connections, meaning the number of messages simultaneously sent*. (default 2 ) * Further attempts in case of error: If the SMTP server or the recipient’s server (for a direct send) doesn’t accept the message, the software can wait a certain number of seconds and retry sending the message one or more times. (default 0) * Pause between attempts: the number of seconds of delay before retrying to send an unaccepted message. (default 5 second) For your reference.
