What is Delivery Automation

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.

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 time gaps between emails – Mimic natural human sending patterns

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

Define sending time windows – 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

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

How to configure:

  1. Toggle Customize to enable this option
  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)

Add delays between consecutive emails to mimic natural human sending patterns and avoid spam detection.

How to configure:

  1. Toggle Customize to enable
  2. Enter the time gap in seconds between each email

Recommended gaps:

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

A longer gap reduces spam risk but means campaigns take longer to complete. Balance speed with deliverability based on your account’s reputation.

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

How to configure:

  1. Toggle Customize to enable day selection
  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

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

How to configure:

  1. Toggle Customize to enable time range selection
  2. Enter start and end times in 24-hour format (e.g., 9 to 17 = 9 AM to 5 PM)
  3. Emails will only be sent within this window

Recommended time windows:

  • 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

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
