Mailcamp does not present sending speed as one fixed number for every account. In practice, how fast a campaign goes out depends on your plan limits, your sending quota, audience size, recipient quality, and whether your account can send normally at that moment.
What affects sending speed in Mailcamp
- Your current plan and sending quota.
- The number of deliverable contacts in the campaign.
- Whether your account still has campaign sending credits remaining.
- Whether your account is temporarily blocked because of deliverability issues such as a high bounce rate.
What happens if you hit a limit
- If you reach a sending quota, a campaign can be paused and continue in the next sending window.
- If you run out of available sending credits, Mailcamp can stop the send until your quota resets or you add more capacity.
- If your marketing channel is bounce-blocked, sending can be disabled until the issue is resolved.
How to check before sending
- Open the campaign Confirm step and review whether sending is currently allowed.
- Check the estimated number of deliverable recipients.
- Review your account quota usage if you think plan limits may be slowing or stopping the send.
How to improve sending performance
- Send to clean, verified audiences so fewer messages are wasted on invalid contacts.
- Start with engaged segments when warming up or troubleshooting delivery performance.
- Keep your sending domain verified and your sender setup healthy.
- Upgrade your plan or use add-ons if you regularly run into quota limits.
Best way to think about sending speed
- Mailcamp sending speed is operational rather than a single advertised throughput number.
- A healthy account with enough quota and a clean audience will usually send more smoothly than an account that is close to limits or has deliverability problems.
If your main question is why a campaign is moving slowly or not finishing as expected, first check quota, deliverable contact count, and deliverability status before assuming there is a platform issue.
