The site itself seems trustworthy, though spammers have been using it for their services. However, there is a link at the bottom of these messages to report spam.
This is an email service for many different companies and organizations. Don't fault the email service if you don't like something from a company or organization they provide service to!
I use this service to send information and updates to our boy scout leaders and scoutmasters.
This site is an excellent service for business and non-profits to send newsletters and information. It meets all the standard and required spam protections and has an instant unsubscribe link on all the emails!
It is a shame that trolls and haters have labeled this as spam. WOT should investigate and correct this site's ratings.
Everyone should flag troll's and haters's comments that don't properly offer first hand experience.
I am just SHOCKED that anyone would even think about listing Halo as a site that has a poor reputation!!! Halo has done so much work for injured and disadvantaged pets! If you get an email from them I encourage you to contribute your time and/or money to them as they provide care and love when no one else would or could. Instead of being listed as a site with a poor reputation it should be listed as a site that has the highest marks there are!
