The core of any outbound email motion is the ability to send emails at a high enough volume and actually have those emails delivered to a target’s inbox - that's what Senders does for us.

We've been working with Senders for about two years so yeah we're happy. You guys have a good set of people in your team and we like this setup around weekly meetings.

Founder, Lovers of Data
There's a lot of really really awesome things. I would say the team is just very open for us. Testing things out - different segments, different copy and they turn around time is just very, very quick which I really, really appreciate and that's been consistent since day one.
Sending a few emails here and there is easy -- sending at a consistently high volume and having them delivered every time is really really hard. Senders handles that for us in spades.
