Two main reasons why the consent from contacts is helpful while importing contacts:
Protect Your Sending Reputation: Importing bulk contacts without proper consent can lead to higher bounce and spam rates, negatively impacting your sending reputation.
Prevent Issues with Purchased or Rented Lists: Even if some lists claim to have opt-in consent, they may not be suitable for marketing communication tools. Contacts from purchased or rented sources are likely to bounce, unsubscribe, mark emails as spam, and may cause block listings.
