List-collection methods and best practice

List-collection methods and list hygiene play a huge part in email deliverability. One small ounce of neglect or ignorance could cause irreversible damage to your domain and IP’s reputation. A purchased or harvested list is a sure-fire way to get caught in a spam trap or a honey pot! Even a single opt-in method can put you in the firing line of malformed email addresses. Although double opt-in adds an extra step for the subscriber, it really is the best way forward, as well as maintaining list hygiene on a regular basis (every 6-12 months) to boost engagement and get those ISPs on your side.

Key Takeaways

1. Why it’s so important to work on building your list.

2. Why it’s just as important to maintain that list clean.

3. Why a purchased or harvested list is literally the worst thing you can do.

I have been working for SMTP2GO for the last 4.5 years where I started off in technical/customer support. I know my fair share about what it takes to get that email delivered into the inbox!”
