Sending over 413+ million emails per month
Why SendPost?
The real problem comes if you are one of the big senders—sending millions of emails per month. That's when managing multiple sending domains, IP-Pools and IP/Domain reputation becomes a severe headache. At that scale, even a minor dip in your email open rate or deliverability impacts your revenue.
You want a solution which helps you understand what broke with your email deliverability and how you can fix it quickly. You don't want to spend hours wading through logs and manually checking if your domain or IP is blacklisted or your sending reputation is low.
You want to be alerted in advance when your deliverability is going to shit. Infact you want a solution which can act on your behalf to prevent that from happening.
You want a reliable partner, powered with a kickass software, who understands how critical email is for your business. And that is why we have built SendPost.
