Frequently Asked Questions
In order to upload templates to your MailChimp account on your behalf, Mail Designer needs your MailChimp API key (a special kind of password).
You can find your API key on your MailChimp. The MailChimp support pages have more information.

MailChimp has free and paid plans. Please visit the MailChimp website for more details and exact pricing information.
MailChimp offers visual "WYSIWYG" and code-based template editing.
However, as every HTML engine works a little bit differently, we recommend that you stick to Mail Designer for editing, as changes made with MailChimp may cause issues with the look or layout of your designs.
If you need to make any changes, simply re-upload a new version of your design and select it for your MailChimp campaign.
On the other hand if you are a HTML code pro, just edit the HTML code with the MailChimp editor untill it fits your needs. We ask for you understanding that we can't offer support for this.
