Pros

“Efficient task automation has freed up my time, allowing me to focus on more creative strategies and high-quality content generation.”

Nikki B.

Aviation Marketing Coordinator

“Act-On recently updated their email composer which made it more cumbersome to design emails.”

Sarah O.

Marketing Manager

“Act-on has been there for our team's marketing efforts.”

Ben R.

Senior Marketing Specialist

Pros

“I work across consulting and B2B media, so I'm constantly building targeted contact lists, and being able to pull verified emails and direct dials right from a prospect's profile, without bouncing between tabs, has genuinely changed how fast I can put a campaign together.”

Ravi, R.

Engineer,

“AI is its real-time search engine, which completely changes how I prospect because it researches contact information across the web the exact moment I request it, rather than pulling from a stale, pre-downloaded database.”

Jan S.

Owner, Chief Researcher

“Seamless AI provided access to a large contact database, helped find verified contact information faster, and reduced the amount of manual research needed.”

VIVEK C.

Founder

Cons

“These marketing efforts have had their ups and downs, and challenges with engagement have been hard to rectify without proper insight.”

Ben R.

Senior Marketing Specialist

“No time wasted on unproductive campaigns.”

Lucy C.

President of Sales

Cons

“AI is its inconsistent data accuracy, which frequently results in frustrating 20% to 30% email bounce rates because its real-time engine lacks a strict multi-source "waterfall" verification process to catch outdated records.”

Jan S.

Owner, Chief Researcher

“Worst of all, their billing and cancellation practices are a total nightmare; they strictly enforce hidden 60-day auto-renewal notice policies that lock you into unexpected, non-refundable 12-month contract extensions that customer support refuses to waive.”

Jan S.

Owner, Chief Researcher

“I find that completely unacceptable. If your cancellation procedure requires the customer to submit a request and then wait for YOUR billing department to contact them, your company should not benefit when your billing department fails to make that contact.”
