What measures do I take if spam complaints, unsubscribes, or bounces occur on my Email Campaigns?

Spam complaints, unsubscribes, and bounces occur in the following scenarios:

• When your contacts have not subscribed to receive your emails
• When contact email addresses are invalid
• When the content is irrelevant to the contacts
• When the sender domain is not authenticated

You can take the following measures to avoid exceeding the threshold levels:

• Clean up your marketing lists at frequent intervals
• Obtain double opt-in from all your contacts
• Send email campaigns only to the contacts that have double-opted in
• Authenticate sender domains using SPF, DKIM, and CNAME records
