First, create either an embedded form or a popup form via the SEMSblast control panel.
When you have finished designing your form you will see a piece of code you can copy. Highlight and copy this code.
Now login to your Webydo account and edit your website.
Click on the WIDGETS tool at the top left of the page and drag a new widget onto your site where you would like your email signup form to appear.
Make sure you have clicked on the new widget that has appeared on your site, and then click the HTML option on the top menu.
On the right of the page you will see a new area called HTML with a "Code" box.
Paste the code you copied in step 2 into the box and then click the UPDATE button to save the changes.
You now have an email signup form on your Webydo site which is connected to your SEMSblast list.
