Send time optimization feature can be used to send bulk campaigns to your audience at the time they are most likely to engage. It analyzes data from your previous campaigns at Mailmodo to determine the optimal time to send emails to each contact. This increases the likelihood of the email being opened and clicked, resulting in a higher engagement rate.

What to Keep in Mind

  1. The send time optimization feature is only applicable when using Mailmodo SMTP to send emails. 

  2. Not recommended for time-sensitive campaigns: If you need to send an email urgently or at a specific time, it is best to use the regular scheduling options.

  3. It might take some time to initiate a send time optimized campaign. So, please schedule at least an hour before

  4. Not recommended for new Mailmodo users as there may not be enough campaign data to analyze the best time to send emails.

To enable send time optimization in Mailmodo, follow these steps:

  1. Go to the Campaign section and create your usual bulk campaign.

  1. Choose your template, add campaign details, and select your audience to arrive at the 'Review and Send' Page. Choose the 'Schedule' option.

    Please note - Send time optimization is not available for A/B test campaigns

  1. The 'Send Time Optimization' option will be selected by default. Add the start date and time for your campaign. Start time is when your STO campaign is scheduled to start.

  2. Click on Schedule campaign and Mailmodo will send emails to your contacts when they are most likely to engage.


Que: How does Mailmodo determine the best time to send the email?

Ans: Maimodo analyzes the engagement history of your contacts. It gives a preferred time to the contacts based on their open and click activities in your previous campaigns sent on Mailmodo

Que: How does the scheduling work?

Ans: Contacts with past engagement history on Mailmodo will be allotted a preferred time, say 10 AM. Once your campaign is STO scheduled for a particular time, emails will be sent in a 24hrs window from the start time. Contacts with preferred times will be sent emails in that window around their respective preferred time. Those having no preferred time will be sent an email once the STO window ends i.e after 24hrs of the start time.

For instance, if the start date and time is 4 pm, 1 AprilAll contacts with ‘Preferred time’ will be sent an email in a 24hrs window starting 4 pm,10 Feb to 4 pm,11th Feb around their preferred time. If no preferred time data is present for any contact, emails will be sent at the end i.e. 4 pm,11 Feb

Que: Is send time optimization available for all Mailmodo plans?

Ans: Yes, send time optimization is available for all Mailmodo plans.
