Emails retooled become spam

Hi,

Just tried the email with the reminder to retool, which only reached nine people and was sent to spam. Do I have any options to avoid this?

As the workflow comes to an end, I even include a delay of one second between each email that is sent.

Sincere Regards,

Following. I have this issue from time to time also. Retool Email often is sent to spam.

I have considered moving to a dedicated email sending platform with higher deliverability rates.
