Since my employer introduced Constant Contact and I signed up to begin hammering out emails and messages to our AmeriCorps Seniors Volunteers, I never realized how much I needed this software in my business life. I spent hours hand entering email addresses separated by commas into my outbox in outlook, just to find that when people with unique email addresses responded... I had no clue who was sending an inquiry. With the ability to upload files like Excel spreadsheets, I can export directly from our Volunteer Database and upload straight into Constant Contact where it automatically lets me toggle my target audience, select a personalized email message for them, and gets our community volunteer opportunities out to over 200 volunteers with EASE! I love that it tells me how many people (and who) viewed our emails so I know who I need to follow up with. If you are responsible for marketing at your organization, Constant Contact is a NON-NEGOTIABLE! Review collected by and hosted on G2.com.

I work as a Dietician & Nutritionist and help manage a small homeopathy clinic. For some time, I used Brevo to send basic email updates like clinic timings, follow-up guidance, and short wellness tips to people who had contacted us.
What I liked most was being able to keep contacts in one place and send the same update to many people at once. Earlier, I had to reply one by one, which took time and sometimes people were missed. With Brevo, I could prepare one clear email and send it to a selected list. This saved time and made communication more consistent. Customer support is Quick and helpful.
The email editor felt easy for simple clinic messages. I did not need much learning to write and format a basic email. After using it a few times, creating a new email and choosing the right list became quick. This helped when I was handling clinic work and content tasks together.
Another useful part was being able to prepare messages in advance. On busy days, having a ready draft helped me send updates without rushing. This was helpful for weekly wellness tips and common clinic information like timings or follow-up guidance.
Overall, Brevo helped make clinic communication more planned instead of random. It reduced repeated typing, saved time on follow-ups, and helped me share health content in a more organized way through email. Review collected by and hosted on G2.com.

Close helps me keep track of patient enquiries and pending replies in one place. I manage diet consultations at a clinic and also get health-related messages online, so it is useful to see who contacted me and what needs to be done next.
