Configure sending limits

In short

How do I set sending limits in Reply?

Set the mailbox limit first in Settings under Email Accounts, then open the sequence Settings tab and configure Max number of emails per day, Max new daily contacts, Delay between each email sent, and Max same-domain contacts per day. Your plan sets the mailbox daily cap, and Max new daily contacts overrides the emails limit.

Goal

A limit configuration that protects deliverability while meeting your volume target, with no surprise about which cap binds first.

Preconditions

Connected email accounts (see Connect a mailbox) and a sequence to configure.

Steps

  1. Start with the mailbox. Two plan values govern it: the default a new mailbox starts at, and the maximum you can raise it to. They are not the same number, and neither is fixed across plans; a save above your plan's maximum is silently reduced to it. To see the value that applies to you, open Settings → Email Accounts, click the mailbox and choose Safety settings: the figure shown there is yours. On the same screen you will find Delay between each email sent. It is already on for every newly connected mailbox, set to a random gap of between 5 and 7.5 minutes: so a new mailbox paces itself at roughly 8 to 12 emails an hour before you change anything. You can set any gap from 20 seconds to 24 hours. If one mailbox serves several Reply accounts, its limit is counted separately in each.
  2. Open the sequence's Settings tab and expand the General settings section.
  3. Set Max number of emails per day – the maximum first-step emails the sequence sends daily, up to 10,000. It cannot exceed the combined daily limits of the mailboxes attached to the sequence.
  4. Set Max new daily contacts – how many new contacts the sequence starts each day. Contacts above the limit wait in the Throttled state until the system prepares them for Step 1. This limit overrides Max number of emails per day and prepares contacts every day, including weekends.
  5. Choose the New daily contact addition mode: Add until capacity (the default) adds only the contacts needed to reach the daily limit and adds none on days the schedule is closed; Add full amount adds the full configured number every day regardless. To skip throttling entirely, enable No limit on new daily contacts – new contacts then move straight into Step 1.
  6. Set Delay between each email sent (seconds) for the sequence. A floor of 120–180 seconds is recommended to avoid provider blocks. If you also set a maximum delay, Reply does not use the minimum; it spaces each send at a random point between the two, so plan your daily maximum around the average of the range rather than the floor.
  7. Turn on Max same-domain contacts per day and set the number to cap how many people at one company you reach per day. The limit does not apply to free domains such as gmail.com, outlook.com and yahoo.com.
  8. To send more than one email to the same contact per day, raise Max daily emails per contact (the default is 1). It does not apply to emails sent within a Manual email step.
  9. Click Save settings and review the sequence schedule – limits apply inside its sending windows.

> How the limits combine: whenever Max new daily contacts is lower than Max number of > emails per day, the contacts limit decides how many first-step emails go out, and the > remaining capacity is used by follow-up steps. Set the contacts limit to the number of new > people you want to reach each day, and the emails limit to your total daily volume.

Ramp up a new mailbox gradually

A new mailbox that starts sending at full volume on day one looks like a spam source. Ramp-up raises its daily allowance a little at a time instead. Turn it on in the mailbox's Safety settings.

Out of the box it starts at 10 emails a day and adds 3 a day; both figures are yours to change.

Five things about it are not obvious and all five cause questions:

  • It counts sending days, not calendar days. A mailbox that sends nothing for a week has not advanced a

week; it is exactly where it was. This is the most common surprise.

  • It raises a floor under your cap; it never lifts the cap. While ramping, the ramp value is your

effective daily limit. Your mailbox limit is still the ceiling.

  • It finishes permanently the moment the climbing figure passes your mailbox limit. It does not keep

going, and it does not resume on its own if you raise the limit later: switch it on again to restart.

  • Switching it off and on again starts over from the opening figure, because the clock restarts the day

you enable it.

  • A change applies from the next day, not immediately.

Ramp-up limits how many you send; the send delay limits how fast. Both apply at once and whichever is reached first is what stops you; a mailbox ramping at 10 a day with a 5-minute delay is held back by the volume, not the pacing.

Expected result

Sends distribute across mailboxes and days exactly as capped: the mailbox limit binds first, then the sequence's daily email and contact limits.

Verification

After the first sending window, per-mailbox counts stay at or under each mailbox's limit and the sequence total stays under Max number of emails per day. Contacts beyond the daily contact limit show as Throttled instead of sending.

What happens next

Sending follows When Reply sends. When a daily limit is reached, the sequence toggle turns yellow until the next window (see Sequence stopping) so check the toggle before raising any cap.

Common mistakes

  • Raising the sequence limit while the mailbox limit binds: nothing changes; raise the right cap.
  • Assuming every plan shares one mailbox ceiling. It is a plan value, and it differs. Read your own figure in Safety settings before sizing a sequence around it.
  • Sizing a new mailbox's day against its daily cap without noticing the send delay is already on. At the out-of-the-box 5-to-7.5-minute gap, a mailbox sending only inside a normal business-hours schedule will not come close to a high daily cap.
  • Confusing Max new daily contacts (contacts starting Step 1) with Max number of emails per day (messages) – and forgetting the contacts limit overrides the emails limit.
  • Sizing the day around the minimum delay when a maximum is also set. The real gap is random between the two, so the achievable daily volume is lower than the minimum implies.
  • Setting the per-email delay too low – 120–180 seconds is the recommended floor.
