&lt;p&gt;From what I&#39;ve heard, some lag is pretty common during a genuine crisis send, especially on the SMS side where carrier throttling kicks in once volume spikes past a certain threshold, so the first wave of recipients gets it almost instantly while the tail end trickles in over several minutes. That&#39;s probably why running voice, SMS, and email together like DialMyCalls does matters more than any single channel&#39;s raw speed, since a multi-channel approach means most people still get something fast even if one channel is the one that lags.&lt;/p&gt;
