Send bulk emails at once with third party SMTP

Greetings,

Most of the Email APIs have a limit on sending BULK emails. Example: With Mailgun we can send 100 emails per hour and with SendGrid we can send one email to 1000 recipients. However, we have some customers who have 6000+ contacts.

We have already tried Mandrill and Mailgun.

Is there anything you can suggest, please?
Any Quick solution? or maybe another gateway to use at this stage?

Thank you

Yes, we recommend using APWT-SMTP for the fastest delivery, most reliable inbox delivery, and more detailed analytics including: bounces, spam complaints, delivery, etc. APWT-SMTP sends at a rate up to 5425 emails / hour.

There are limits imposed by the email receiving side that limit how many emails they will accept per hour. The limits applied by major ISPs can also change if suspicious behavior is detected. When an ISP sees five bounces within a certain timeframe, they may send a throttling message that tells the sending server to slow down or stop sending for a certain period of time.

Thanks for your answer.
For some of our clients, we can not use APWT SMTP. That is why we are looking for some other platform.

Thank you.
