If you notice, this email sender comes with a little credit at the bottom when you send your mails. This allows us to keep the tool free for people who just want to get their message across.
What is the inbox rate of this mass email software
It depends on the mail server you are using, but this software allows you to use Google's own SMTP servers which of course is trusted by Google. We have seen that the inbox rate for this little free tool can be higher than paid tools out there. By inbox rate, we do not mean promotions, updates or social tabs.
Is there a paid bulk email sending software available instead?
Yes there are other tools out there but if you prefer a lightweight tool like this, send us an email and we may consider providing a lifetime free edition without ads if the demand is high.
