I like the CRM integration, the simplicity of use, analytics, email builder, and the fair price to use it. I think Zoho has done a really great job putting this together and making it an invaluable tool for business needs. I can segment my subscriber's lists, run drip emails, autoresponders, plus all the other bountiful tools to use for speaking my most engaging subscribers. I also like the Review process before sending to make sure it has the best deliverability (that's priceless!)
I could write for days the things I like about it, it just has so much to offer.
I don't like the social widgets they have in the editor. The social icons are grainy and not clear. I did a workaround with their template and made my own widget bar which looks amazing, clear and custom. The only pitfall to that is the Report Summary doesn't reflect my custom widget clicks in the Campaign Reach section as it was designed to do. I have to tally up one by one manually in the Recipient Activities 'Clicked" menu (time killer and impossible with a big list!!).
I wish they had more email builder tools like other competitors, more column choices and layouts. Better text flow with images would be great, I can't get it to work how I'd like.
Lastly, the media uploader needs an overhaul. It's finicky and looks outdated. One issue, it won't let me upload the same file back to back. Sometimes, I upload an image and don't like the way it looks, then I go back and edit it in Photoshop/Illustrator and save with the same filename, then I upload that file again, and the uploader won't load the file unless I change the filename (usually by adding a 1 to the end of the filename).
Always look at other email campaign managers to make sure this is the right fit for your needs. If you have Zoho CRM, then I highly recommend to just use Zoho Campaigns.
When I first started my job here, they used to use Zoho CRM for doing mass emails (small contact list at the time), but with the business growing and collecting more leads, it was necessary to use an email campaign manager to manage the lists, comply with CAN-SPAM regulations, and have the better tools to build the emails, make custom, and really dig deeper into the analytics of our efforts. The benefits really speak for themselves. This gave us the full integration to Zoho CRM and opened up a better way to speak to our customers. I am an Administrator of our CRM and the Marketing Director, so I use all of it!
