  import { MessagesSendAngularService } from '@mailchain/nameserver-angular';

  // add to constructor
  constructor(
    private sendService: MessagesSendAngularService,
  ) { }

  // add to function and then execute logic in the callback
  myFunction() {
    let outboundMail = this.sendService.initOutboundMail()

    const protocol = "ethereum" // change accordingly or use function params
    const network = "ropsten" // change accordingly or use function params

    outboundMail.message["headers"]["from"] = "0x123...98"
    outboundMail.message["headers"]["reply-to"] = "0x123...98"
    outboundMail.message["headers"]["to"] = "0x999...111"
    outboundMail.message["public-key"] = "0x5555...555"
    outboundMail.message["subject"] = "Your subject"
    outboundMail.message["body"] = "Your message body"

    // Process message data here
    this.sendService.sendMail(outboundMail, protocol, network).subscribe(res => {
      this.messageResult = {
        status: res['status'],
        statusText: res['statusText']
