Hi @keyur161095,
We are very sorry for the inconvenience caused by that update.
Our intention was to disable Weekly Email Summary for all existing Lite and Multisite installations. There was a bug in the plugin code that did not trigger the migration code that was responsible to prevent these emails from sending, but this migration was not triggered on plugin updates via WP automatic updates or via external WP management tools.
We released version 3.0.3 shortly after, which fixes this issue. Please be sure to update to this latest version when you have a moment. After the update, your sites will not send these Summary emails.
After updating, you may want to make sure weekly email summaries are disabled by heading to WP Mail SMTP > Settings > Misc and checking that the checkbox for Disable Email Summaries is enabled.
For more information on this issue, we initially learned about the error here: https://wordpress.org/support/topic/your-weekly-wp-mail-smtp-summary-sent-despite-being-disabled/
Let me know if you have any questions, and we apologize again for the inconvenience we caused with this error.
Thank you!
