You can use separate subdomains for different types of marketing campaigns. For example, you could use one subdomain for marketing campaigns and another for transactional emails.
How does it help? It protects the reputation of the main domain where italy business email list your website is located. Although the reputation of a subdomain may affect the reputation of the main domain, the impact is usually minimal. Additionally, there is greater flexibility and control since the reputation of one subdomain has no impact on other subdomains. Even if spam complaints occur, you can maintain high deliverability and protect the reputation of your main domain by leveraging subdomains.
3. Domain name warm-up
Internet service providers are often wary of new senders. Without an established reputation, they will scrutinize messages sent from new domains and IPs more carefully.
To overcome this problem, it is necessary to warm up your IP and domain by starting with a small number of emails and gradually increasing the sending rate over time. Each new subdomain you set up for email sending should be warmed up.
4. Email list hygiene
Maintaining a clean mailing list is just as important as growing it organically. To reduce the likelihood of spam complaints, don’t overlook best list management practices:
Use double opt-in. This process ensures that your subscribers actually want to receive your emails and allows you to avoid spam traps, invalid addresses, and bot subscriptions in your list.
Eliminate hard bounces. Exclude email addresses that generate hard bounces. If you use an email service provider, they will most likely handle this for you.
Do not send to unsubscribed users. Comply with unsubscribe requests promptly and ensure that no further messages are sent to these individuals.
Handle spam complaints. A spam complaint is sent when a recipient reports your message as spam. Spam complaints are handled by the Feedback Loop (FBL) service provided by your ISP. If you sign up for the FBL service, notifications about user-reported spam are usually sent back to the sender. Reputable email service providers handle feedback loop messages for their customers and automatically exclude recipients who report emails as spam from their active mailing lists.
Delete inactive users. Monitor recipient engagement data regularly. If a subscriber hasn't opened your emails in the past 3-6 months, consider removing them from your list. This proactive approach reduces the likelihood of encountering spam traps while maintaining a healthy and active subscriber list.
