BOMA's email tool has a great way to share a video with your contacts.
Create your email and once you've chosen your template and opened up the email editing tool, follow these easy steps:
Click on the Content tab
Click on the Video tile - drag and drop it under your logo
Click on the Add a URL button
Add the URL or link of your video - to the panel on the right.
The preview image will automatically be generated - you can set this in YouTube or Vimeo.
You can also change the play icon if you'd like to customise it.
If you'd like to add some text to introduce your video:
Click on the Content tab
Click on the Text tile and drag it into your template above the video and below your logo.
Replace the placeholder text with your message
