Pros

“Clean interface, easy setup, flexible list and data management, scalable for larger sends, usable template builder”

Martina S.

“The ability to quickly and easily integrate the corporate marketing platform into SendGrid to enable campaigns and help ensure message delivery.”

Shane S.

CEO

“SendGrid offers robust API support, which makes it easy for developers to integrate email sending into applications.”

Himanshu V.

Senior software developer

Pros

“Kit’s up to 10K email subscribers on the free tier is generous on its face, especially because it includes landing pages, forms, broadcasts and tagging. But if you allow yourself to accumulate 10,000 subscribers on the free tier, subscriber 10,001 is going to cost you, as of the time of this review, either $116/mo or $1,390/yr.”

Faydra D.

Most-Things-Web Consultant

“Overall, I think Kit is very good at what it is clearly built to do: help creators grow and email an audience without getting buried in technical complexity. But it is not the best fit for every small business, and it is not the platform I would automatically recommend when customization, reply-routing flexibility, advanced reporting or budget-sensitive scaling are high priorities.”

Faydra D.

Most-Things-Web Consultant

“I've been doing web work since 1999, and in every CRM and email marketing platform I ever used for my own purposes and/or setup up for clients I was immediately directed to set up a sending domain.”

Faydra D.

Most-Things-Web Consultant

Cons

“The pricing levels are not worth the money because our e-commerce traffic is at its peak, and customer service is painfully slow when we have urgent account problems or some data management failures.”

Amir H.

E-Commerce Manager

“I’ve run into bugs that the support team hasn’t been able to help with and often feel limited by the automation capabilities.”

Hayley A.

Marketing Manager

“Free Plan have strict limit for number of mail you can send, that make difficult for upgrade without testing it proper.”

Tarun S.

Web developer

Cons

“Also, you are not allowed to use one email for sending and another email as "reply-to" on ANY plan, free or paid.”

Faydra D.

Most-Things-Web Consultant

“Going from $0 to (at the time of this review) $33/mo or $390/yr is not budget-friendly to bootstrapping solopreneurs, and I primarily work with bootstrapping solopreneurs.”

Faydra D.

Most-Things-Web Consultant

“Reporting is pretty basic and the landing page templates feel dated.”
