Pros

“The ability to see who is on the website, what pages they’ve been looking at and their keyword searches helps me to do everything from understand intent leads better to helping to plan ABM campaigns based on behaviours.”

Jamie G.

Senior Account Manager

“Pretty positive, you get exactly what you pay for- for an SME that's just starting out with email marketing it gives you the basic toolset to segment your audience and send email campaigns with some metrics on performance.”

Jake L.

Global Marketing Manager

“At first, the possibility to track our website visitors and being able to contact new customers”

cyrille I.

Manager

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

“Throughout my time using their service, there was no mention of their terms and conditions, that you have to cancel before 30 days of the renewal. And there was no reminder at all.”

Sherry T.

Marketing Specialist

“We figured out the application does not meet our needs, but as you are engaged for more than one year, you are re-conducted even if you explain that the needs are not fulfilled.”

cyrille I.

Manager

“So the value that can actually be gotten from their platform will be smaller. Upon realizing that the platform was a waste of time and money, I discovered that my subscription had been auto-renewed with no means of cancellation.”

Sherry T.

Marketing Specialist

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email bounce rates because its real-time engine lacks a strict multi-source "waterfall" verification process to catch outdated records.”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.”
