Use a 3rd Party ESP like Lead Liaison

Reputable ESPs provide many advantages. For example, they:

1. are white listed with the ISPs
2. are tied into feedback loops with ISPs (to receive notice of spam messages or blacklisting)
3. have software programs to ensure messages are CAN-SPAM compliant
4. have authentication procedures such as Domain Keys, DKIM, SenderID, and SPF
5. can help you troubleshoot issues and avoid making mistakes
6. keep up on the email marketing and email deliverability industry

Lead Liaison provides these six advantages with every software subscription license.
