Email deliverability is crucial for successful outreach campaigns. One of the critical factors affecting deliverability is the timing of your emails. In this guide, we'll break down how Manyreach's timing controls work, so you can optimize your campaigns for maximum inbox placement.
Two Essential Timing Controls
Manyreach gives you two distinct settings to control the timing of your emails. Note that they use different units: the sender delay is in minutes, the campaign delay is in seconds.
1. Sender Level Delay (minutes)
What it is: The minimum time a specific email address must wait before sending another email.
Where to find it: In Sender settings under "Minimum Delay Between Emails".
Recommendation: We recommend keeping this setting at 10 minutes for optimal deliverability. This prevents any single email address from appearing automated while still allowing for efficient sending.
2. Campaign Level Delay (seconds)
What it is: The minimum time between any two emails in your campaign, regardless of which sender is used.
Where to find it: In Campaign settings under "Daily Sending Limits". It's set in seconds: the default is 30 seconds, the minimum is 1 second and the maximum is 290 seconds.
Example: If set to 60 seconds, your campaign will send a maximum of one email every minute, alternating between available senders.
How These Settings Work Together
The relationship between these two settings determines the overall rhythm of your campaign. Let's see how they interact in different scenarios:
Scenario 1: Many Senders (10 email addresses)
Settings: Campaign Delay = 60 seconds, Sender Delay = 10 minutes
9:00 AM: Sender 1 sends email
9:01 AM: Sender 2 sends email
9:02 AM: Sender 3 sends email
...and so on through all senders...
9:09 AM: Sender 10 sends email
9:10 AM: Sender 1 can send again (10-min sender delay expired)
9:11 AM: Sender 2 can send again
In this case, the campaign progresses steadily at around one email every minute (factoring in a randomized delay), cycling through all senders before reusing any single sender.
Scenario 2: Few Senders (3 email addresses)
Settings: Campaign Delay = 60 seconds, Sender Delay = 10 minutes
10:00 AM: Sender 1 sends email
10:01 AM: Sender 2 sends email
10:02 AM: Sender 3 sends email
10:10 AM: Sender 1 becomes available again (10-min sender delay expired)
10:11 AM: Sender 2 becomes available again
10:12 AM: Sender 3 becomes available again
Here, the campaign quickly uses all available senders, and then must wait for the sender delay to expire before continuing. With few senders, the sender delay becomes the bottleneck.
Finding Your Optimal Settings
When to Prioritize Campaign Delay
Goal: Control overall campaign pace
Best for: Larger lists with multiple senders
Example: To send 120 emails evenly throughout a 2-hour period, use a 60-second campaign delay (with at least 10 senders, so the 10-minute sender delay doesn't slow you down).
When to Prioritize Sender Delay
Goal: Protect individual sender reputation
Best for: Ensuring natural sending patterns for each email address
Example: We recommend keeping the sender delay at 10 minutes to maintain good deliverability while still allowing efficient sending.
Best Practices for Better Deliverability
Mimic Human Behavior: Based on the delay you've set, Manyreach uses random delays between emails to appear more natural than fixed intervals.
Start Conservative: Begin with our recommended 10-minute sender delay, and adjust the campaign delay (in seconds) based on your volume needs.
Match Your Volume: More emails require more senders to maintain healthy sending patterns.
Finding the Right Balance
The perfect timing setup depends on your specific needs:
High-Volume Campaigns: Use more senders with a 30-second campaign delay and a 10-minute sender delay.
Urgency: Keep the 10-minute sender delay and lower the campaign delay based on urgency. The minimum campaign delay is 1 second.
Sender Protection: Never reduce the sender delay below 10 minutes, to protect your domain reputation.
By understanding and properly configuring both timing controls, you'll maintain better deliverability while achieving your campaign goals.
Remember that these settings work alongside other important factors like email content, authentication, and domain reputation to determine overall deliverability success.
