There is no single magic setting: several elements work together.

What deliverability depends on




- Sender authentication
- Reputation of the domain and sending address
- List quality and cleanliness
- Message content and structure
Ongoing work, not a one-off
In Cantù we look after sending with a technique designed to pass antispam filters and we monitor results over time, without promising 100% guaranteed delivery. This applies to companies between Milan and Lugano. For domain setup see domains, mail and servers.


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.
Sender reputation is the opinion that mail providers form of your domain based on past sends: complaints, bounces, interactions. It is built over time and must be protected. In Cantù we set up sender and sending pace to protect it, for companies in Como and Milan.
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.
The open rate shows how many people open the newsletter, the click rate how many click a link inside it. Together they show whether subject line and content work. From Cantù, in the province of Como, we help companies in Brianza and Milan read these indicators without promising guaranteed results.
