How Many Warm-up Emails Per Day for a New Google Workspace Inbox?

Short answer: Start with 30 warm-up emails per day if your domain reputation is neutral or healthy.

Use Ramp-up for at least 14 days so you do not jump to 30 on day one. Follow a simple 1:1 rule where warm-up volume matches cold email volume.

With Google mailboxes, it’s generally safer to run higher volume and scale over time, because these inboxes are typically easier to maintain than Microsoft once they’re warmed correctly.

Most Google Workspace senders run 30 to 50 cold emails per day early on. That’s why your warm-up target often lands in the same range. If you want the conservative default, start at 30 and scale up after you’ve been stable.

Why Google mailboxes are usually easier to maintain at higher volume

In practice, Google Workspace mailboxes tend to be more forgiving once you establish consistent sending behavior and engagement. That does not mean you can spike volume. It means that after you warm up properly and keep your sending pattern steady, scaling to moderate daily volumes is usually smoother compared to Microsoft inboxes.

The key is building trust first:

• Start conservative
• Ramp up gradually
• Keep sending times consistent
• Do not start cold outreach too early

A practical rule that keeps you safe: match warm-up to cold volume (1:1)

Warm-up works best when it resembles your real outbound behavior.

A simple guideline:

• Sending 30 cold emails/day? Warm up around 30/day‍
• Sending 50 cold emails/day? Warm up around 50/day

This matters because many deliverability problems start when teams warmup gently, then suddenly push cold sending volume far beyond what the inbox has been conditioned for

What volume should you choose for Google Workspace?

Here’s the simplest way to choose your daily warm-up volume:

Safe baseline (most teams)

• 30 or less warm-up emails per day

Common working range (once stable)

• 30 to 50 warm-up emails per day

If you are new to warm-up, start at 20 emails per day. If everything stays stable for a couple weeks, scaling toward 40 to 50 is usually reasonable on Google mailboxes.

Important: This assumes your domain reputation is neutral or healthy. If you’re recovering from deliverability issues, seeing spam placement, or working with a brand-new domain, ramp more slowly and consider a lower initial target.

Ramp-up: how to increase volume without making it obvious

Even if your goal is 30/day (or 50/day), do not start there on day one.

What a good ramp-up looks like

• Ramp up over at least 14 days
• Increase daily volume gradually
• Avoid a rigid pattern (like the same increase every day)

A ramp that looks “too perfect” can look automated in a bad way. The goal is steady, natural growth.

If you’re using Mailivery warm-up, you set your target and enable ramp-up. Daily increases are randomized so the volume builds gradually without a predictable formula.

How to set this up (quick checklist)

Warm-up volume is controlled by your Emails Per Day setting.

Recommended setup for a new Gmail or Google Workspace inbox

• ‍Target (Emails Per Day): 30‍
• Ramp-up: On‍
• Ramp-up period: at least 14 days‍
• Sending schedule: only during your normal business hours

Once you’ve been stable at 30, you can raise the target (for example, toward 40 or 50) and let ramp-up handle the climb.

When should you start cold emailing?

This is the most common way people hurt a domain.

If your domain is a few months old

• Warm up for at least 14 days before starting cold email

If your domain is brand new

• Warm up for 30 to 60 days before starting cold email

Brand-new domains have very little trust. Give them time.

If you want to scale higher on Google, do it like this

Google mailboxes are often easier to maintain at moderate daily volume, but the safe path is still incremental.

A simple scaling approach:

1. Start at 30/day with ramp-up enabled
2. Hold steady until performance is stable
3. Increase your target in small steps (for example, toward 40, then 50)
4. Keep warm-up running while you scale cold outreach

The two rules that protect you:

• Avoid spikes
• Keep warm-up volume close to your cold volume (1:1)

Common mistakes to avoid when warming-up

1) Starting cold email before warm-up is complete

Rule of thumb:

• Domain is a few month sold: wait 14 days
• Domain is brand new:wait 30 to 60 days

2) Treating warm-up like a one-time checklist item

Warm-up is a continuous process. If you turn it off after “finishing,”you lose the steady signals that help keep performance stable.

3) Sending outside your normal hours

Only send warm-up emails during the hours you normally send cold email.

Avoid:

• Late nights
• After hours
• Weekends (unless you truly send on weekends)

Warm-up should match real sending behavior.

4) Scaling cold volume faster than warm-up

This is the silent killer. If cold sending climbs but warm-up stays flat, you create a mismatch in behavior. Keep the 1:1 relationship as you scale.
