To personalize the content of each message using the fields you’ve imported, Easy Mail Merge uses a variable text delimiter. Variable text (that is going to be personalized on each email) is defined using the ^ character. Please make sure you are NOT using this character on your email content (text, links, etc), otherwise Easy Mail Merge will misinterpret it as a variable field and it will trigger the above error because that field is not found in the imported mail merge data.

Please make sure you are not using Microsoft Word as the email editor for Outlook messages. To switch to the Outlook internal email editor, please go to your Outlook Options menu -> Mail Settings -> uncheck the option to use MS Word as the email editor.

If you notice that ALL outgoing mass emails are being quickly returned as undeliverable, then most likely you have hit the maximum limit of emails allowed by your mail server provider.

Here is a page showing the daily limit of most popular mail server providers: http://www.emailaddressmanager.com/tips/server-smtp-limit.html.

The Easy Mail Merge TRIAL version limits you to maximum 10 emails per session. The licensed version does not have any limit. The only limit is the one enforced by your mail server provider. In order to avoid having your messages rejected, you have to make sure you are not exceeding this limit. If your mail server does not have such a limit, you can send as many mass emails as you wish to.
