Emails sent via crm to gmail show "sent via zohocrm"

Emails sent via crm to gmail show "sent via zohocrm"

When I send an email to a gmail account through the crm, the gmail recipient receives the email, but it shows as coming from "myname sent via zohocrm". 

I have created the spf records on my domain and I believe I have  configured the CRM correctly. 

When I send and email from zoho email, then it does not show the "sent via"

Is there a solution to this. 

Thanks in advance for the help
