Risky emails deserve a second look before you send a campaign.
Sharing API keys
Keep API keys private and revoke them if they are exposed.
Starting campaigns before verification finishes
Wait until your bulk list is completed and reviewed before sending emails.
18. Best Practices
Verify before every campaign
Check your data before sending to save time and reduce bounces.
Clean regularly
Don’t wait too long between list cleanups.
Download clean lists
Use the clean export when you only want the best contacts.
Monitor credits
Keep an eye on your balance so jobs do not stop unexpectedly.
Keep API keys private
Store keys in a secure place and use different keys for different tools when needed.
