- Avoid Mondays: Upload contacts and send email on other days
- Upload Early: Allow up to 4 hours before seeing or mailing to your contacts
- Allow more time for larger Campaigns to reach inboxes
- Larger Lists: Wait until end of workday or weekends (more than 5,000 contacts)
Thank you! This helps our instance run more smoothly for our 1,000+ users.
If you upload a large list outside these guidelines, we will remove it from the Contact Label process and ask you to re-upload it at a better time. If you know when you need your list to be ready, you can contact us to get a recommendation for when to do your upload.
Here’s a review on the contact upload process from our Knowledge Base (KB).
