6 Tips for Sending Bulk Email Newsletters 2008 Aug 16

Topics: email — by jonah ellison
  1. Write HTML like it’s 1999 – Email clients and web clients such as Gmail love to strip out CSS within <style> tags. For this reason, use inline CSS. Also, using tables to build your newsletters is a safe idea as well, since the float property isn’t always supported. Outlook 2007 is extremely limited when rendering HTML–no background CSS images, no forms, no custom bullet images.

  2. Don’t use PHP’s mail() function – This function opens and closes a connection to your mail server every time, which is extremely inefficient. It is possible to write your own bulk email sender in PHP, however! Use an SMTP class for more control and speed.
  3. In the “To” field, always have the user’s email address – The easiest way to have your email eaten by a spam filter is to not use the user’s actual email in the “To” field. Some like to send out more emails by placing multiple email addresses within the BCC header, but this will add spam points to the email.
  4. Set up an SPF TXT record for your domain name – This is another anti-spam filter technique to make sure your emails get through. If you look at the source headers of an email, you may see an entry that says Received-SPF: neutral or Received-SPF: fail. It should only take 5 minutes to set this up and make it say “pass.” For example, my domain register allows me to add DNS TXT records, so for the host field I would type “httpremix.com.” and for the address field I would add "v=spf1 a mx -all" (quotes included for the TXT).
