Mailpro does not enforce a rigid daily cap. Sending volume depends on your plan and your monthly credit quota.
Pro tip: for lists > 50,000, we recommend spreading sends across several hours to protect your reputation.
Volume by plan
Every Mailpro plan ships with a credit quota. 1 credit = 1 email sent. You can:
- Send your entire quota in one day if needed
- Spread it across the month for better deliverability
- Top up credits for a one-off large send
Compare plans and quotas on the pricing page.
Best practices by volume
| Volume | Recommendation |
|---|---|
| < 10,000 | Single batch send |
| 10,000 - 50,000 | Spread over 2-3 hours |
| 50,000 - 200,000 | Spread across the day |
| > 200,000 | Spread over 2-3 days |
Recipient server limits
Gmail, Yahoo and Outlook accept only so many messages per hour from one IP. Mailpro auto-throttles sends to avoid being rate-limited.
First large send (warm-up)
- Start with your most engaged contacts
- Ramp volume up over 2-3 weeks
