Denis L.

Customer service rep

Pros

“It's a reliable and easy-to-use email marketing tool that integrates seamlessly with Gmail, making it simple to create, personalize, schedule, and track campaigns without switching platforms.”

Saksham K.

Marketing manager

“It makes email outreach much easier by allowing me to manage campaigns directly from Gmail, schedule emails, track open rates, and automate follow-ups.”

Karthikeya S.

Admin

“I was able to send over 300 emails and landed an agent along with 250 emails for a campaign pitch and allowed me to make each email individualized.”

Jackie P.

Model and Creative Director

Cons

“The marketing campaign features are not as advanced as some dedicated email marketing platforms.”

Denis L.

Customer service rep

“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

Cons

“The sequence logic is less sophisticated than what I had access to in Intercom Series previously, but that's an unfair comparison given the price difference.”

Rene B.

Partner

“There are limitations in email template customization, a potential learning curve due to its feature-rich interface, deliverability issues related to its reliance on Gmail's infrastructure, and a lack of built-in CRM functionalities”

Joseph C.

Director of Operations

“No matter what tool you use, failing to warm up your domain and validate your email list will ruin your sender reputation.”
