Upgrading isn't too expensive either with packages starting at $8.04 per month for a 30,000 monthly email allowance.
Ok, so Constant Contact isn't a totally free product, however, it's listed because it offers a great free trial. For 30-days free users have access to all of Constant Contact's marketing tools (one of the longest trials on the market).
Constant Contact provides numerous email templates, a drag and drop editor for customisation and excellent email tracking. The next package up from the trial is £5 per month, so it's still a reasonable price for small businesses and startups.
