Starting a brand-new mailbox with 30 campaign emails on day one is a guaranteed way to damage your domain score. New mailboxes need to earn trust gradually — a concept called ramp-up. GetReplies automates the entire ramp-up process so you don't have to manage it yourself.
How ramp-up works
When you turn on ramp-up for a mailbox, GetReplies takes full control of your daily campaign limit. You don't set a fixed number — the system sets it for you, and changes it over time based on what it's observing:
Phase | Timeline | Warmup emails/day | Campaign emails/day | What's happening |
Week 1–2 | Days 1–14 | ~25/day | 3–5/day | Mailbox is new. Warmup dominates. Tiny campaign volume. |
Week 3–4 | Days 15–28 | ~22/day | 8–12/day | Campaign limit starts climbing. Warmup holds steady. |
Month 2 | Days 29–60 | ~20/day | 15–25/day | Campaign volume grows each week. Warmup begins to taper. |
Month 3 | Days 61–90 | ~15/day | 25–50/day | Mailbox is established. Stable volume. Warmup continues. |
Bounce event | Any time | ↑ increases | ↓ reduces | Bounce detected. System automatically pulls campaign back and increases warmup to repair score. |
The bounce feedback loop
This is one of the most important things GetReplies does that no other tool in this category offers. The system actively monitors your bounce rate and manages action automatically.
Bounce detected. A campaign email bounces (the address no longer exists, or the server rejected it).
Campaign limit reduced. The system reduces how many campaign emails it sends per day — immediately.
Warmup limit increased. The system increases warmup activity to counteract the bounce signal and repair the domain score.
Gradual recovery. As your domain score stabilises, the system gradually restores your campaign limit.
This all happens automatically. You don't need to detect the bounce, calculate how much to pull back, or manually adjust anything. The system handles it.
This is why list quality matters more than list size
The bounce feedback loop means that a list full of stale or unverified email addresses will directly damage your sending capacity — the system will keep pulling your daily limit down to protect your domain.
A list of 200 verified, current email addresses will always outperform a list of 2,000 unverified ones. Enrich and verify your contacts before sending — this protects both your deliverability and your domain score.
When to use ramp-up vs. when to skip it
| ⚙ Ramp-up settings guide |
New mailbox (< 1 month old) | Turn ON ramp-up. Let the system manage volume from scratch. |
Young mailbox (1–3 months) | Turn ON ramp-up. Start conservative and let it grow. |
Established mailbox (3+ months) | Turn OFF ramp-up. Set campaign limit manually at 30–50/day. |
Returning mailbox (was dormant) | Turn ON ramp-up. Treat it as new — it has lost warmth. |
Warmup setting | Always ON — regardless of mailbox age or ramp-up status. |
Can I override the ramp-up?
Yes. If you switch off ramp-up, you set the daily campaign limit manually. The system will respect that limit and not change it automatically. Warmup still continues in the background.
We recommend only doing this for mailboxes that are at least 3 months old and have a healthy sending history. Forcing high volume on a new or recovering mailbox will damage your domain score faster than the ramp-up would have helped it.
