To Send email from AEM, follow the steps written below:
Gmail SMTP Server could also be used to relay messages from your device or application. If you connect using SMTP, you can only send mail to Gmail or Google Apps users; if you connect using SSL/TLS, you can send mail to anyone.
If your device or application supports SSL – connect to smtp.gmail.com on port 465.
To connect with SSL, you need to provide a Google username and password for authentication.
You can connect it in this way:
- CONFIGURE MAIL SERVER
Go to the Felix configuration by hitting the url – http://localhost:4502/system/console/configMgr then open the Day CQ Mail Service and configure like this
- ADD A TEMPLATE
A template is basically created in /etc/notification. The MailTemplate class provides email text templating functionality. Templates are nt:file nodes in the repository representing a text file (or html will also work, as in this case).
The template will create a structure of how your email will look like. The ${subject} and ${message} act as the replacement variables.
And then write the code as follows:
- CREATE A SERVLET
Create a servlet and write the following code snippet :
1
2
| @ReferenceMessageGatewayService messageGatewayService; |
This will get all the values with the request as parameters in the form of a map.

| @SuppressWarnings("unchecked")parameterNames = request.getParameterNames();parameters = new HashMap<String, String>();while (parameterNames.hasMoreElements()) {final String key = parameterNames.nextElement();parameters.put(key, request.getParameter(key));} |
MailTemplate will create a mail template

2
| Resource templateRsrc = request.getResourceResolver().getResource("/etc/notification/send-email.html");String mailId = request.getParameter("mailId"); |
- ATTACH IMAGES
Email attachments can send any file attached with the mail

| EmailAttachment attachment = new EmailAttachment();attachment.setPath("<image-Path>");attachment.setDisposition(EmailAttachment.ATTACHMENT);attachment.setDescription("Any Description");attachment.setName("Any name you can set");final MailTemplate mailTemplate = MailTemplate.create(templateRsrc.getPath(), templateRsrc.getResourceResolver().adaptTo(Session.class));final HtmlEmail email = mailTemplate.getEmail(StrLookup.mapLookup(properties), HtmlEmail.class);email.addTo(mailId); |
The getEmail method returns the chosen (type argument) email implementation, as long as the type extends Email and has a publically accessible default constructor. Out of the box the three email implementations provided by the Apache Commons Email library can be used: SimpleEmail, HtmlEmail, and MultiPartEmail.

| messageGateway = messageGatewayService.getGateway(HtmlEmail.class);messageGateway.send(email); |
MessageGateway is an Object capable of sending a message to a recipient. This is a ServiceProvider to be used to register as an OSGI service. Gateways can be accessed via MessageGatewayService.
- ATTACH IMAGES FROM DAM
To attach an image from the dam you can fetch the image in binary format and send it to the desired recipient in this way,

| Resource imageNodeRes = request.getResourceResolver().getResource("/content/dam/indeximg/anil-gupta-nav-img.jpg/jcr:content/renditions/original");Node imageNode=imageNodeRes.adaptTo(Node.class);Node contentNode = imageNode.getNode("jcr:content");Binary imageBinary = contentNode.getProperty("jcr:data").getBinary();InputStream imageStream = imageBinary.getStream();ByteArrayDataSource imageDS = new ByteArrayDataSource(imageStream,"image/png");email.attach(imageDS,"Some Image","Some Description"); |
- EXPLICITLY EMBEDD IMAGES
Images can be Embed explicitly in this way but this will violate the mail Template and send mail in its own way.

| URL url = new URL("<Any URL>");String cid = email.embed(url, "<Any Name>");email.setHtmlMsg("<html><body><img src=\"cid:"+cid+"\"></body></html>"); |
