Incredibly easy to use. There are tonnes of players that do what they do. Some do more that what they do, some less. If you ask me, they have the most robust solution for their core function to track opens and clicks.

Pros :

  • The best software of all the well knows competitors.

Cons :

  • Can't think of any.

What else can I say about Sendgrid? It's the single best SMTP service; it's a fabulous service if your architecture is already in the cloud; it's cheap; the people are great.

In short: I can’t believe this tool is free. I mean, there are paid versions – but I can’t believe the free version is free. And even though 90% of my time spent doing SEO is not on link building, I am what you’d call a “heavy user” of email.  I know a promising tool when I see it.

I would recommend against SendGrid. We started using SendGrid using a relative old list. We immediately ran into issues with this list and had our account suspended. Checking the same list with MailChimp we found that MailChimp warned us about the quality issues before sending, allowing us to clean the list, and SendGrid just closed our account after sending and running into high bounce rates. After that we had to deal with a highly critical customer service department that treated us like a headmaster treats a child. Contrastingly, working with MailChimp is a breeze. I realize that using an old list was actually a mistake on our side. However, I believe a service can protect you against making beginner's mistakes in stead of punishing you for them.
