Which is the best tool, other than MailChimp, to automate emails with a personal touch?

I've been having to send emails to users on a constant basis and it's extremely important for our ops to have them respond to them. I don't like MailChimp since they look really "newslettery", so I've been sending them manually through my Gmail account in order to give that personal touch that users respond to. However, it's really time-consuming and I need a better solution. Is there another tool the PH Community recommends? I'm pretty sure I've received a bunch of emails from products that look like they were personally typed but they're automated. ¿Suggestions?

    Been using Sendgrid since a while and I have its API installed as well to deliver both transactional and marketing emails. As with everything else, it might take a while to get used to their interface and features are comprehensive. They have a good knowledge base with step-by-step resources. Segmentation, contact management and analytics are a part. They also have deliverability/reputation reporting and scoring.
