Available Settings

Batch Size

Default: 10 messages

Controls how many messages are sent in each processing cycle. Higher values send faster but may:

• Trigger rate limits on your email provider
• Overwhelm your mail server
• Impact deliverability

Value	Use Case
10-25	Small businesses, conservative sending
25-100	Medium businesses, established senders
100-500	High-volume senders with good reputation

Start Low

If you're new to email marketing, start with a lower batch size and increase gradually as you establish your sender reputation.

Cancel Window

Default: 5 minutes

The delay before the first batch starts sending. This gives you time to:

• Review the recipient list
• Cancel if you spot an error
• Make last-minute changes

Value	Use Case
1 minute	Quick sends, experienced users
5 minutes	Standard safety buffer
15-30 min	Large campaigns, extra review time needed
60 min	Maximum review time for critical campaigns

Batch Delay

Default: 60 seconds

The wait time between sending batches. Longer delays:

• Spread sending over more time
• Reduce load on mail servers
• Improve deliverability for large campaigns

Value	Messages per Hour (batch size 10)
30 sec	1,200
60 sec	600
120 sec	300
300 sec	120

Send Warning Email

Default: Enabled

When enabled, company administrators receive an email before each campaign starts sending. The warning includes:

• Campaign name
• Number of recipients
• Scheduled send time
• Link to cancel if needed

This provides an extra safety check, especially useful when multiple team members manage campaigns.

Calculating Send Time

To estimate how long a campaign will take to complete:

Total time = Cancel Window + (Recipients / Batch Size) × Batch Delay

Example: 500 recipients, batch size 10, 60s delay, 5min cancel window

5 min + (500 / 10) × 60s = 5 min + 50 min = 55 minutes

Best Practices

For Small Lists (< 100 contacts)

• Batch size: 10-25
• Cancel window: 5 minutes
• Batch delay: 30-60 seconds

For Medium Lists (100-1,000 contacts)

• Batch size: 25-50
• Cancel window: 5-15 minutes
• Batch delay: 60 seconds

For Large Lists (> 1,000 contacts)

• Batch size: 50-100
• Cancel window: 15-30 minutes
• Batch delay: 60-120 seconds
• Consider sending at off-peak hours

Troubleshooting

Sends are too slow

Increase batch size or decrease batch delay. Be cautious not to exceed your email provider's rate limits.

Getting rate limited by email provider

Decrease batch size and increase batch delay. Check your provider's sending limits.
