Easiest Way To Send An Email


The functionality of sending emails in Business Central is based on ‘Email’ and ‘Email Message’ codeunits. We will use the methods in these codeunits to create them.

We can use ‘EmailMessage.Create‘ and ‘Email.Send‘ to create a very simple email.


As you can see, we are using the new ‘Email Scenario‘ feature. Where we can define which emails send documents. The main purpose of this feature is to decouple email accounts from sending emails. You can find this feature on the ‘Email Scenario Assignment‘ page.


We have the possibility to extend the enum ‘Email Scenario’ with new options and add our own email scenarios. For this example, we will be using the ‘Default’ option.

How To Send An Email With Attachments


For sending attachments, we will use an InStream, an OutStream, and the ‘Temp Blob‘ codeunit. In this example, we will attach a sales invoice in ‘pdf’ format. First, we will ask for the invoice to attach. We achieve it by running the request page of the report and saving the filters applied in the ‘ReportParameters’ variable.


The email will look similar to the following:


If you want to learn more about InStreams and OutStreams follow the article below:


How To Send An Email With Preview Window


The preview window is the page where the user can see and modify the email before sending it. We can use the method ‘Email.OpenInEditor‘ for this purpose.


Before sending, we can modify or check the email. The page will look similar to this one. Here we can also attach any document:


How To Improve The Sending Process


Until now, we have been using some basic methods for our functions. Let´s see how we can enhance the sending process.

Here is a list of improvements we are going to make.

  • Create a list of recipients
  • Html format for the preview window
  • Selection of both sending options
  • Email.OpenInEditorModally
  • Show Error if the email couldn´t be sent

With the third overload of the function ‘EmailMessage.Create’, we can pass a list of recipients. Also, we can choose the Html format for the body.


We will use the ‘Email.OpenInEditorModally‘ to handle the response of the user. With ‘Email.OpenInEditor’ we couldn´t. An enum called ‘Email Action’ will tell if the user clicked on ‘Sent’.


We are going to use ‘Dialog.StrMenu‘ to let the user decide if they want to preview the email or not before sending it.

Then, we add to a list of every recipient we want for the email.

Finally, we can show an error if the message couldn´t be sent.

The final code will look like the following.


Because we chose Html format, we have access to the edit ribbon:


How To Create an Html Body


An email body can be simple as the one we have been using in the previous examples. However, if we want to improve our email appearance we can use an Html body.

We can even add our email signature with an image at the bottom. This is an example of how to do it:


This is the preview of the email just created:


Bonus: How To Check Email Status


Business Central provides two pages to check if our emails were sent or failed, these are ‘Email Outbox‘ and ‘Sent Emails‘.

Email Outbox


Here you will find failed emails, drafts, pendings if they were queued, and mails in sending process:


Sent Emails


On the following page, we will see a list of emails sent successfully. We can see several information and also resend them if we want.


Source code:

 procedure SendEasiestEMail()
    var
        Email: Codeunit Email;
        EmailMessage: Codeunit "Email Message";
    begin
        EmailMessage.Create('alberto.soben@businesscentralgeek.com', 'This is the subject', 'This is the body');
        Email.Send(EmailMessage, Enum::"Email Scenario"::Default);
    end;

        TempBlob.CreateInStream(InStr);

        EmailMessage.Create('alberto.soben@businesscentralgeek.com', 'This is the subject', 'This is the body');
        EmailMessage.AddAttachment('FileName.pdf', 'PDF', InStr);

    procedure SendEmailWithPreviewWindow()
    var

        EmailMessage: Codeunit "Email Message";
    begin
        EmailMessage.Create('alberto.soben@businesscentralgeek.com', 'This is the subject', 'This is the body');
        Email.OpenInEditor(EmailMessage, Enum::"Email Scenario"::Default);
    end;

    procedure SendEmailWithPreviewWindowHtmlFormatBody()
    var
        Customer: Record Customer;
        Email: Codeunit Email;
        EmailMessage: Codeunit "Email Message";
        Body: Text;

        Body := '<h3>TO MESSRS: ' + Customer.Name + '</h3>ATT : ACCOUNTING DEPARTMENT </br> </h3> <hr></br>Your current balance with us is:</br></br><strong>' + format(Customer.Balance) + '</strong></br></br><hr></br>Best regards,</br></br>Financial Department</br></br>Spain</br> <img src="https://businesscentralgeek.com/wp-content/uploads/2022/06/Imagen3.jpg" />';

        EmailMessage.Create('alberto.soben@businesscentralgeek.com', 'This is the subject', Body, true);
        Email.OpenInEditorModally(EmailMessage, Enum::"Email Scenario"::Default);
    end;

    procedure SendEMail()

        Selection: Integer;
        OptionsLbl: Label 'Send,Open Preview';
        ListTo: List of [Text];
    begin
        Selection := Dialog.StrMenu(OptionsLbl);
        ListTo.Add('alberto.soben@businesscentralgeek.com');
        EmailMessage.Create(ListTo, 'This is the subject', 'This is the body', true);
        Cancelled := false;
        if Selection = 1 then
            MailSent := Email.Send(EmailMessage, Enum::"Email Scenario"::Default);
        if Selection = 2 then begin

            MailSent := Email.OpenInEditorModally(
                EmailMessage, Enum::"Email Scenario"::Default) = Enum::"Email Action"::Sent;
            Cancelled := not MailSent;
        end;

        if (Selection <> 0) and not MailSent and not Cancelled then
            Error(GetLastErrorText());
    end;



That´s all. Hope you find it helpful.
