Does sending emails in smaller batches improve deliverability?

From what I understand, some corporate servers will block emails from reaching their final destination if they see a lot of emails with the same content coming through at the same time.

Does anyone have experience with sending out emails in smaller batches over time? When does it make a difference?

TIA

Patrick

Use the Send Email condition in your flow step. Then click Add Choice. Now with the choices, you can get as granular as you want. My 2 favorites are alphabetical and random sample.

Example conditions for flow:
If email address starts with a; b; c  send email. Default Choice: do nothing
wait one hour
If email address starts with d; e; f  send email. Default Choice: do nothing
wait one hour. yada yada yada

 or

If random sample is 25 (representing 25% of the whole list)  send email. Default Choice: do nothing
wait one hour
If random sample is 25  send email. Default Choice: do nothing
wait one hour
If random sample is 25  send email. Default Choice: do nothing
wait one hour
If random sample is 25  send email. Default Choice: do nothing

Would the following flow work so that you do not send the email to the same person multiple times as Patrick had indicated?

If random sample is 25  send [01 EMAIL]. Default Choice: do nothing
wait one hour
If was sent email is [01 EMAIL] - Do nothing
If random sample is 25  send [01 EMAIL]. Default Choice: do nothing
wait one hour
If was sent email is [01 EMAIL] - Do nothing
If random sample is 25  send [01 EMAIL]. Default Choice: do nothing
wait one hour
If was sent email is [01 EMAIL] - Do nothing
If random sample is 25  send [01 EMAIL]. Default Choice: do nothing

It has never happened to me before. In the random sample field did you place a "%"? I just input a number (i.e. 10% = 10, 20% = 20). I always make sure that all the numbers in the random sample equal to 100.
 Try the email route and see if it does the same thing.

Hi Bentacular,

Did you ever check your log/results file? I just set it up for a smartlist of 20 emails and in steps of 10%. The first 2 hours it went okay.Then it started repeating sending the email to the same people in the second sending. Fortunately I tested it on a sample size for 20 people so I only annoyed 2 people but for whatever reason, it didn't work for me.

Any insights why it started sending emails to people already sent to?

TIA

    Hi Bentacular, how do you set up a random flowstep that sends out a list over 4 different times?

    TIA for any guidance

    I like the idea of doing it hourly as I can also see response/open rates per hour. How do you set up a random selection flow step?

    I usually throttle emails using the wait step of 1 hour in the flow using random selection or alphabetically

      Definitely in small batches and I try to stagger the delivery of the emails by regions, or by time zones.

      Thanks for your insights.

      Any idea of batch size and time in between sendings? Would a sending of 100 emails per domain every hour yield good results? Or should we do 10 emails every 6 hours?
