Andrzej Duda-Poznański

Since 2017 has been making sure your emails don't end up in the trash

Andrzej joined Impuls Poznań Consulting in September 2017. He is not a typical marketer for pretty pictures. He deals with what isn't seen, but what decides on the earnings – the technical side of the mailing. Over the last years, he has checked exactly 1,482 mail servers. For him, only numbers count and whether the message reached the customer. If your offers end up in spam, Andrzej will find the cause in the server logs in less than 45 minutes.

In 2023, Andrzej pulled 89 companies from Greater Poland out of spam filters. The average deliverability growth for his clients is 34.7% within the first two weeks of cooperation. He doesn't promise miracles; he simply fixes DNS records and cleans databases of inactive addresses. It simply works. No more manual work and wondering why no one replied to your offer.

Andrzej has a specific approach to work. He starts every project with a hard audit. In March 2024, he saved a contract for a wholesaler from Poznań worth 142,000 PLN. Their invoices were going to spam due to incorrect DKIM record configuration. Andrzej fixed it in 114 minutes. We checked this on 423 clients – the technical correctness of the domain is the foundation without which marketing doesn't exist.

You won't hear fluff from him about building relationships. You will hear about SMTP protocols and IP blacklists. Andrzej believes that emails should earn, not annoy Google or Outlook servers. His record is increasing message open rates from 12% to 48% in just 19 days for a transport company from Jeżyce. Only hard data from the administrator panel count.

Privately, Andrzej is a resident of Poznań's Winogrady. He transfers his precision from work to home – he fixes every fault immediately because he believes errors don't disappear on their own. At Impuls Poznań Consulting, he is responsible for technology not standing in the way of your sales. If you are looking for someone who will stop talking about theories and just unblock your inbox – Andrzej is that man.
