A sluggish start saw John Askey’s side fall behind inside five minutes when Jack Bridge was on hand to convert from close range following Harry Cardwell's header back across goal.
Pools began to settle, however, and eased themselves into the game before Tom Crawford levelled the scores with a fine finish from the edge of the area.
Askey’s side had one or two chances to take the lead before the break but it would be the Shrimpers who hit the front once more when Gus Scott-Morriss headed in from Callum Powell’s cross early in the second half.
Askey was forced into a change in the midst of falling behind for a second time when Emmanuel Dieseruvwe was taken off but his replacement Joe Grey made an instant impact when netting Pools’ second equaliser of the day.
And Hartlepool went on to claim all three points when Charlie Seaman scored his second goal in as many games to claim a third straight win.
And this is how Pools were rated in their Roots Hall success:
