I'm evaluating FileMaker now. The Email campaign functionality sounds wonderful, but a little too good to be true. From the beginning my question was, "How can FileMaker ensure the deliverability of my email the way commercial internet solutions do?"
The email campaign PDF in the business starter kit includes the following information on page 14:
Things You Must Do
1. On December 16, 2003 the Controlling the Assault of Non-Solicited Pornography and Marketing Act of 2003 (CAN-SPAM Act) was signed into law. It establishes a framework of administrative, civil, and criminal tools to help America’s consumers, businesses, and families combat unsolicited commercial email, known as spam.
2. While your email to your customers, is not technically spam because your customers have requested to be added to your list, you should always do these two things when sending email.
- Include your organization’s physical mailing address at the bottom of your email. Add a sentence similar to this, “This email is being sent from ABC Company, 1234 Main St., Paso Robles, CA 93446.
- Provide info on how a recipient can opt-out of receiving your email by adding a line after your physical mailing address at the bottom of the email that is similar to this, “You are receiving this email because you or someone used this email address to subscribe to this email. To unsubscribe from this email, please reply with REMOVE in the subject line to discontinue receiving Special Offer emails from us.”
3. Also please refer to the complete CAN-SPAM Act online to be sure you’re complying with all the requirements where appropriate. Read more at: http://www.ftc.gov/bcp/edu/pubs/business/ecommerce/bus61.shtm
I have little experience with email campaigns. My non-expert opinion on your situation would be that possibly people are marking your emails as SPAM, and the servers are learning from this and proactively canning your emails. But for all I know, your headers could very well be the problem as well. Any experts with an opinion?
