SalesTarget.ai sets specific limits on the number of emails you can send per day per account to ensure your domain reputation stays intact — especially during the warm-up phase.
By following these limits, you maintain a positive sender reputation, which is essential for avoiding spam filters and ensuring your emails reach your recipients' inbox.
Domain Limit
Each domain can support up to 5 email accounts.
All accounts under the same domain share the same reputation. If one account sends too many emails too quickly and gets flagged, it can negatively affect all other email accounts under that domain.
This is why warming up all email accounts within a domain together — at a controlled pace — is critical. Treating each account in isolation without considering domain-level reputation is a common mistake that can hurt deliverability across all your accounts at once.
Email Account Limit
Each email account is allowed to send up to 30 emails per day.
This limit helps prevent overuse of the account and ensures it does not raise red flags with ISPs. Gradually increasing toward this limit as part of your warm-up plan helps the account build a good reputation and avoids triggering spam filters.
To increase total sending volume safely, the recommended approach is to add more email accounts and more domains — not to increase the per-account daily limit beyond what is safe.
Example:
1 domain × 5 email accounts × 30 emails/day = 150 emails/day safely from that domain
Build Trust with ISPs
ISPs look for patterns in email behavior. If you send too many emails too quickly from a new domain or account, it can appear suspicious.
A well-warmed domain demonstrates to ISPs that you are a legitimate sender — reducing the chances of being flagged, rate-limited, or blacklisted. Following the per-account daily limit is the simplest way to keep your sending pattern looking natural.
Maximize Open Rates
As you build your sender reputation by following these limits, recipients are more likely to see and open your emails. Warmed-up accounts with good reputations consistently produce better open rates than accounts that skipped the warm-up process or exceeded safe sending limits.
Better open rates also signal positive engagement back to ISPs, reinforcing your reputation over time in a virtuous cycle.
Summary
- Each domain supports up to 5 email accounts
- Each email account sends up to 30 emails per day
- All accounts on a domain share reputation — warm them up together
- To scale volume, add more accounts and domains — not higher per-account limits
- Following these limits protects deliverability and improves open rates over time
