Email Warm-Up Ramp Planner

Map a sending ramp that gradually increases daily email volume while warming a new domain or IP. Enter your total warm-up volume and days available to see recommended start and finish volumes, the daily step-up, and how many inbox engagements that cadence should generate.

Aggregate messages you need to send before scaling campaigns.
Number of calendar days allocated to domain warm-up.
Defaults to 50. Enter how many emails you plan to send on day one.
Defaults to 35%. Helps translate sends into engaged inbox volume.

Deliverability results depend on list hygiene, content quality, and engagement. Validate volumes with your ESP or deliverability partner before scaling production sends.

Examples

  • 12,000 total emails, 21 days, start 50/day, 35% open rate ⇒ Start at 50 sends/day, finish at 1,100 sends/day with a 50.00 daily increase. Average daily volume: 575.00 sends/day across 21 days. Projected engaged opens: 4,830 (35.00% assumed). Ramp meets the target volume.
  • 6,000 total emails, 14 days, defaults for optional fields ⇒ Start at 50 sends/day, finish at 807 sends/day with a 58.18 daily increase. Average daily volume: 428.50 sends/day across 14 days. Projected engaged opens: 2,100 (35.00% assumed). Ramp meets the target volume.

FAQ

How should I adjust for weekends or holidays?

Enter the number of sending days instead of calendar days if you pause campaigns on weekends, or rerun the model with a longer period to simulate downtime.

Can I model throttling by mailbox provider?

Yes. Reduce the final daily volume to your most restrictive provider limit and rerun the calculator to see how many extra days you need to reach the target.

What if I want an exponential ramp?

Use this calculator to get the total warm-up capacity, then design your own exponential curve that matches the same starting point and total volume.

Does this include reply automation warm-ups?

No. Pair this with your reply automation cadence to ensure total daily sends across tools stay within acceptable warm-up thresholds.

Additional Information

  • Linear ramp assumes inbox providers reward consistent daily increases; adjust manually if you prefer exponential growth.
  • If your starting volume exceeds the average needed per day, the calculator trims it so the ramp remains positive.
  • Projected open volume multiplies the achieved sends by the expected open rate to give a sense of engagement milestones.
  • Extend the warm-up period or run multiple ramps if you manage parallel sender reputations (e.g., transactional vs. marketing).
