Red Oxygen's 2 Ways SMS is must have feature to ensure customer satisfaction. **Rating:** 5.0/5.0 stars **Reviewed by:** Ranjita G. | Project Manager, Mid-Market (51-1000 emp.) **Reviewed Date:** December 05, 2023 **What do you like best about CompleteSMS?** The best thing about Red oxygen is its long text option that allows more than 150 characters and it also allows two-way communication with a template option, making the overall process easy and customer-friendly. **What do you dislike about CompleteSMS?** The thing I disliked about Red Oxygen is its pricing option is not available in all currencies. **What problems is CompleteSMS solving and how is that benefiting you?** Red Oxygen helped us solve bulk customer queries and its templates and two-way text messages helped us cater to multiple responses in a short duration which reduced the cost associated with customer support. ### 2. Awesome service **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Veterinary | Small-Business (50 or fewer emp.) **Reviewed Date:** December 21, 2023 **What do you like best about CompleteSMS?** This service makes it so muhc easier to contact employees in the work setting. Even if you need to text schedule reminders, or ypdates/available shifts it is a quick easy way to get it sent out to everyone. A lot of people don't have as easy access to their email as they do their phones so I have seen a big difference in how fast employees respond! **What do you dislike about CompleteSMS?** Some people think they are spam messages. **What problems is CompleteSMS solving and how is that benefiting you?** It's helping us access employees easier and quicker, since most people do not check their emails multiple times a day. ### 3.
