Yes they can send the emails, but the email that is native to SuiteCRM is lacking in a lot of ways. We have over 110 users and no one liked using their email. We moved everyone over to Thunderbird with the Opacus plugin. This way they have all the features they were used to and their incoming and outgoing emails are archived. Email should be one of the strongest features of any CRM in my mind and for some reason they do not seem to think it is that important, or at least how much they have done to improve it reflects that. We love everything about Suite, but the email.
So, at this point they can not completely do all their work in the app. I think they can do just about everything but email their customers and them be archived. This will be huge once there is a solution to this. There is so much work with customers that are done in the CRM using emails and I have never understood why SuiteCRM has the weakness. The internal email is not a good experience. We use Thunderbird and the the Opacus plugin. With email being so important in business today, I never understood why that was the weakest feature in their whole system. I hope QuickCRM can develop a solution in your app. Thank you for your help.
What have have done is to go into a Lead, clicked on their email address, it then opens up an email which we composed. We confirmed the email was sent and delivered. This was all done in the app. So the app allows us to send email by clicking on the email address. If I understand you correctly, the emails that are sent have no way of being saved in the history of Lead, Account, etc. currently. In order for that to happen they have to go directly into the SuiteCRM site and send from there. We seldom use the offline mode. All of the sales reps iPads are equipped with cellular service.
