What is Delivery Automation

Introduction

Delivery Automation helps you send emails gradually and strategically, avoiding spam filters and Gmail restrictions. Sending too many emails too quickly damages your sender reputation and can get your account temporarily suspended.

This feature gives you precise control over when, how fast, and on which days your emails are sent—essential for maintaining high deliverability and staying within Gmail’s limits.

Plan Availability

Delivery Automation is available on Plus and higher plans.

What is Delivery Automation?

Delivery Automation controls the pacing of your email campaigns. Instead of blasting all emails instantly, you can:

✅ Set daily email limits – Stay within Gmail’s quotas and avoid account suspension

✅ Add a delay between emails – Use a fixed pause or a random range

✅ Choose specific sending days – Send only on weekdays or your highest-engagement days

✅ Set sending hours – Send only during business hours or optimal times

This controlled approach is critical for:

• Warming up new accounts without triggering spam filters
• Maintaining sender reputation on established accounts
• Maximizing engagement by sending at the right times
• Complying with Gmail’s policies and daily quotas

How to Configure Delivery Automation

1. Set Maximum Emails per Day

Control your daily sending volume to stay within Gmail’s limits and protect your account.

How to configure:

1. Turn on Set daily limit
2. Enter your desired daily email limit
3. If your contact list exceeds this limit, BetterMerge automatically spreads sending across multiple days

Recommended limits:

• New accounts (< 1 month old): Start with 20-50 emails/day
• Warming up (1-2 months): Gradually increase to 100-200 emails/day
• Established accounts: Use up to 500 (Gmail) or 2,000 (Workspace)

Warmup Strategy

For new accounts, start conservatively and increase by 50-100 emails per week. Learn more in our Deliverability Guide.

2. Set the Delay Between Emails

Add a pause between emails to control how fast your campaign sends.

How to configure:

1. Turn on Set email delay
2. Choose a delay type:
   • Fixed: every email waits the same number of seconds
   • Random range: each email waits a random number of seconds between the minimum and maximum you enter, for example 30-90 seconds
3. Enter whole seconds between 3 and 3,600

When this option is off, or your plan doesn’t include custom delays, BetterMerge waits 10 seconds between emails.

Changing plans

Custom delays are available on plans that include them. If you move to a plan without them, campaigns that already have a delay saved switch to the 10-second default for emails that haven’t been scheduled yet, which can make them send faster. Your saved delay is kept and applies again if you upgrade.

Recommended delays:

• New accounts: 60-120 seconds (1-2 minutes)
• Established accounts: 30-60 seconds
• High-volume sending: 10-30 seconds

A longer delay spreads sending out but makes campaigns take longer to finish. With a random range, the estimate before launch shows a range of days.

You can change delivery settings after a campaign starts: open its report and click Edit delivery. Changes apply from the next scheduled email.

3. Choose Sending Days

Optimize engagement by sending only on days when your audience is most active.

How to configure:

1. Turn on Choose sending days
2. Check the days you want emails sent
3. Emails will only be delivered on selected days

Recommended schedules:

• B2B campaigns: Tuesday-Thursday (highest open rates)
• B2C campaigns: Any day, including weekends
• New accounts (warmup): Monday-Friday only for the first month

Consistency Matters

Maintain consistent sending patterns. Sending 500 emails Monday then nothing for a week looks suspicious. Spread volume evenly across your selected days.

4. Set Sending Hours

Send emails during specific hours when recipients are most likely to engage.

How to configure:

1. Turn on Set sending hours
2. Choose a start and end time, for example 9:00 AM to 5:00 PM
3. Emails are only sent within these hours, in the time zone shown below them

Recommended sending hours:

• B2B (office workers): 9:00-17:00 (9 AM - 5 PM)
• B2C (consumers): 10:00-20:00 (10 AM - 8 PM)
• International audiences: Adjust for recipient time zones

Test and Optimize

Track open rates by send time and adjust your window based on actual engagement data. What works for one audience may not work for another.

Best Practices

✅ Start conservative – It’s easier to increase volume than recover from being flagged

✅ Monitor metrics – Track bounce rates, spam complaints, and open rates after enabling automation

✅ Adjust based on results – If metrics decline, slow down your sending

✅ Maintain consistency – Don’t alternate between 500 emails one day and 0 the next

✅ Combine with other strategies – Use with Email Verification and clean lists

Summary

Delivery Automation is your insurance policy against spam filters and account restrictions. By controlling pace, timing, and volume, you ensure emails reach inboxes while building a strong sender reputation.

Set it once, let it run automatically – BetterMerge handles the timing and pacing so you can focus on writing great emails that convert.
