you can try with this code and test sending to a GMAIL address

// For complete examples and data files, please go to GitHub - aspose-email/Aspose.Email-for-.NET: Aspose.Email for .NET examples, plugins and showcase projects
// The path to the File directory.
string dataDir = RunExamples.GetDataDir_Email();
string dstEmail = dataDir + “EmbeddedImage.msg”;

// Create an instance of the MailMessage class and Set the addresses and Set the content
MailMessage mail = new MailMessage();
mail.From = new MailAddress(“test001@gmail.com”);
mail.To.Add(“test001@gmail.com”);
mail.Subject = “This is an email”;

// Create the plain text part It is viewable by those clients that don’t support HTML
AlternateView plainView = AlternateView.CreateAlternateViewFromString(“This is my plain text content”, null, “text/plain”);

/* Create the HTML part.To embed images, we need to use the prefix ‘cid’ in the img src value.
The cid value will map to the Content-Id of a Linked resource. Thus will map to a LinkedResource with a ContentId of //‘barcode’. */
AlternateView htmlView = AlternateView.CreateAlternateViewFromString(“Here is an embedded image.”, null, “text/html”);

// Create the LinkedResource (embedded image) and Add the LinkedResource to the appropriate view
LinkedResource barcode = new LinkedResource(dataDir + “1.jpg”, MediaTypeNames.Image.Jpeg)
{
ContentId = “barcode”
};
mail.LinkedResources.Add(barcode);
mail.AlternateViews.Add(plainView);
mail.AlternateViews.Add(htmlView);
mail.Save(dataDir + “EmbeddedImage_out.msg”, SaveOptions.DefaultMsgUnicode);

Dim credentials As NetworkCredential = New NetworkCredential("from@domain.com", "password")
Dim client As IEWSClient = EWSClient.GetEWSClient("https://outlook.office365.com/ews/exchange.asmx", credentials)
Dim mail As MailMessage = New MailMessage()
mail.From = New MailAddress("from@domain.com")
mail.[To].Add("one@gmail.com")
mail.[To].Add("two@gmail.com")
mail.Subject = "This is an email"

Dim plainView As AlternateView = AlternateView.CreateAlternateViewFromString("This is my plain text content", Nothing, "text/plain")

' Create the HTML part.To embed images, we need to use the prefix ‘cid’ in the img src value.
' The cid value will map to the Content-Id of a Linked resource. Thus  will map to a LinkedResource with a ContentId of //‘barcode’. 
Dim htmlView As AlternateView = AlternateView.CreateAlternateViewFromString("Here is an embedded image.<img src=cid:barcode>", Nothing, "text/html")

Dim barcode As LinkedResource = New LinkedResource("11.jpg", MediaTypeNames.Image.Jpeg) With {
    .ContentId = "barcode"
        }
mail.LinkedResources.Add(barcode)
mail.AlternateViews.Add(plainView)
