Instytut ZwiązkówOwner at Instytut Związków

Impressive Growth, Respected PartnerOur collaboration with Delante has delivered excellent outcomes. We began with very poor visibility and many of our crucial keywords were not even indexed. Through their optimization efforts, link-building, and content creation, our website now ranks at the top of search results for our key phrases, leading to a major boost in traffic and visibility. We value their clear strategy, consistent execution of goals, and transparent reporting. We are extremely satisfied with both the results and the partnership. It's also noteworthy that even Delante's competitors regard them with high respect.

Easy Choice for Email/SMSI have worked with Frank and his team on the creative for a few different clients and can tell you there is no agency that will work harder for you. No matter the hour or the problem, they are on the clock searching for creative solutions to fit your needs. They are incredibly attentive, fast to execute, and always available when needed.

IT Now Technologies - Go-To for Spot-On B2B Data and Real Results It was pretty early on, after we launched our first email campaign using their B2B list. The bounce rate was dramatically lower than anything we'd seen before, and the engagement rates were surprisingly high. We started getting genuine responses and setting up quality meetings almost immediately.
