A newsletter ends up in spam when providers' filters consider it unreliable: unauthenticated sender, poorly maintained list or suspicious content.

It happens to serious companies in Como, Brianza and Milan too, often because of technical details that cannot be seen from the outside. Understanding the causes is the first step to fixing them.

Why it happens

The most common causes

  • Sender domain without correct authentication (SPF, DKIM, DMARC).
  • Lists with old, wrong or never-interested addresses.
  • Subject lines and text that resemble unwanted messages.
  • Heavy images with very little text and messy code.
  • Sudden sends that are very different from the usual.

There is no single reason: providers weigh many signals together.

How we step in

From the technical check to the list

From our Cantù office (Como) we check configuration, list and content, and adopt a sending technique designed to reach the inbox. For domain authentication see domains, mail and servers.

Services of interest

Deliverability is the ability of a newsletter to actually reach the recipient's inbox rather than spam. It depends on authentication, reputation, list quality and content. In Cantù, for companies between Como and Milan, we handle the sending technique without promising guaranteed delivery.

SPF, DKIM and DMARC are domain authentication systems: they state which servers can send, sign the messages and set how failed checks are handled. For companies in Como and Brianza, the NewVisibility team in Cantù configures them together, to give providers a trustworthy sender.

To reduce the spam risk you authenticate the domain, keep the list clean, write balanced subject lines and text, and send regularly. Nobody can guarantee 100%, but the Cantù team takes care of these factors for companies in Como, Brianza and Milan.

Subscriptions and unsubscriptions are managed automatically by connecting the website form to the platform: whoever signs up joins the right list, whoever leaves stops receiving sends. From Cantù we configure these flows for companies in Como and Milan; for consent matters, speak with your consultant or DPO.

To recover contacts who did not open you resend the message to those who have not read it, changing subject line and time, and check the quality of the list. NewVisibility, in Cantù near Como, sets up this automation for companies between Como, Brianza, Milan and Lugano.
