Email warm-up is an essential step in Aesthetix CRM to ensure your emails land in recipients' inboxes rather than spam folders. This process helps build a strong sender reputation, especially when using a new subdomain for email marketing.
Your subdomain is new and needs time to establish credibility.
Even though it is linked to your root domain, email providers assess subdomains separately.
Warm-up helps prevent emails from being marked as spam.
Clients who skip warm-up may experience low email deliverability and open rates.
Best practice is to warm up the email domain for at least the first two campaigns.
Aesthetix CRM provides a warm-up calculator to guide your email sending strategy.
Go to Resources > Calculators on the Aesthetix CRM website.
Select Email Blast Warm-Up Calculator.
Enter the number of contacts in your email list.
Indicate whether you've sent emails before from another platform.
View the recommended drip settings for sending emails.
For small lists (under 10,000 contacts), the sending limits remain relatively stable.
For larger lists (over 10,000 contacts), the system recommends slower sending rates initially.
Example:
5,000 contacts → No more than 100 emails per hour or 1,000 emails per day.
15,000 contacts (never emailed before) → Starts much slower to avoid being flagged.
After 1–2 weeks, sending volume can increase.
Best Practice: Do NOT send time-sensitive offers during the warm-up phase—use evergreen content instead.
Once you have your email warm-up plan, you can set up your email blast inside Aesthetix CRM.
Go to Email Marketing and create your campaign.
Choose a pre-built email template or create a new one.
Click Send or Schedule and select Batch Schedule.
Set Start Date → Choose when you want the emails to begin sending.
Set Batch Sending Rate:
Example: 100 emails per hour
Preferred method: Send small batches every few minutes rather than a large batch at once.
Example Configuration:
If sending 100 emails per hour, set it to send 3 emails every 2 minutes (for a total of 90 per hour).
Set Time Restrictions:
Choose active sending times (e.g., 7:30 AM – 6:30 PM).
Avoid sending on weekends if necessary.
Select your contact list and apply click tracking or UTM tracking (optional).
Click Schedule.
After scheduling, monitor your bulk actions to adjust the batch quantity if needed.
Go to Contacts > Bulk Actions.
Click on the three-dot menu next to your scheduled campaign.
Select Edit Batch Quantity.
Increase the sending limit as needed:
Example: After 3 days, increase from 100 emails/hour to 300 emails/hour.
Set 10 emails every 2 minutes to achieve 300 emails/hour.
Click Update Batch Quantity.
Once the campaign starts sending, track:
Open Rates (should be 25% or higher).
Deliverability (check for high bounce rates).
Spam Complaints (keep as low as possible).
If open rates are low, consider:
Improving email content.
Adjusting the sending frequency.
Ensuring proper domain authentication (SPF, DKIM, DMARC).
Email warm-up gradually builds sender reputation. If you rush the process, your emails may land in spam. Customers who follow this process have 40–55% open rates after full warm-up. Once your domain is warmed up, you can send larger volumes without issues.
By following these steps, you’ll maximize email deliverability and ensure your messages reach the right inbox!
