Send times are incredibly inconsistent. Sometimes it will take up to two hours to send an email. So for example, if you're sending a time sensitive email, be sure to schedule it a couple hours earlier than you originally want. I talked with support, and they gave me a couple reasons for this:
-Their servers can only send 20,000 emails per hour (for the entire platform). That means if you're looking to hit your contact database, you're sharing the servers with everyone else. You can apparently pay more $ and get a private server so your send times are consistent.
-Apparently their internal team reviews all emails for spam and broken links, and you have to wait for their reviews to go through.
So overall, Benchmark lacks a core function of any email service provider - SENDING EMAILS WHEN SCHEDULED.
If you're trying to send time sensitive emails, Benchmark is not the platform for you. Maybe it would work for B2C, but for B2B companies trying to get the correct messaging at the correct time, Benchmark's functionality falls short.
We were hoping to use Benchmark for nurture campaigns, however, it's inconsistent send times made it a failure for us.
