How to show validation error for each row for email and fax for loop items using angular8

i am using Angular8 with bootstrap, i have made inputs to be from a loop array. If there is any validation error for email or fax number, it is throwing validation error, then if there is error for email in the first row, if there is any error for fax in second row it shows, if in the 3rd row if email is entered wrongly and made correct, the first row validation error also goes off. But i want to show validation error for all rows of there is an error with respect to fax or email respectively.

HTML:

              <input type="text" class="form-control" placeholder="Email" name="Recepient"
                          formControlName="recipients" *ngIf="data.value.deliveryMethodId == 178"
                          (focusout)="validationErrorOnFocusOut('emailvalid',data)"
                          [ngClass]="{ 'is-invalid': emailsubmitted  && data.controls.recipients.errors}"
                          pattern="^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$" autocomplete="off">
              <div *ngIf="(emailsubmitted && data.controls.recipients.errors)" class="invalid-feedback">
                <div *ngIf="(emailsubmitted && data.controls.recipients.errors)">
                  Please enter valid email</div>
              </div>
              <input type='text' prefix="+1 " mask=" (000) 000-0000" class="form-control"
                          placeholder="Recepient" name="Recepient" formControlName="recipients"
                          *ngIf="data.value.deliveryMethodId == 179" maxLength="18"
                          (focusout)="validationErrorOnFocusOut('fax',data)"
                          autocomplete="off"
                          [ngClass]="{ 'is-invalid':faxsubmitted && data.controls.recipients.errors.mask}">
              <div *ngIf="faxsubmitted && data.controls.recipients.errors.mask" class="invalid-feedback">
                <div *ngIf="faxsubmitted && data.controls.recipients.errors.mask">Please enter valid fax number
                </div>
              </div>

TS:

  public validationErrorOnFocusOut(name, data) {
    if (name == "emailvalid") {
      if (data.controls.recipients.status === "VALID") {
        this.emailsubmitted = false;
      } else {
        this.emailsubmitted = true;
      }
      if (
        data.controls.recipients.value === "" ||
        data.controls.recipients.value === null
      ) {
        this.emailsubmitted = false;
      }
    } else if (name == "fax") {
      if (data.controls.recipients.status === "VALID") {
        this.faxsubmitted = false;
      } else {
        this.faxsubmitted = true;
      }
      if (
        data.controls.recipients.value === "" ||
        data.controls.recipients.value === null
      ) {
        this.faxsubmitted = false;
      }
    }
  }
