Tom Eaves' last-minute equaliser saw the Shrews end a dispiriting run of six successive home defeats with a 1-1 draw against the League One leaders.
Jackson, taking charge for the second time following the resignation of Graham Turner, said: "It wasn't a great day conditions-wise with the wind and the pitch was heavy but we're pleased with the point and I think we deserved that.
"I think it's just the start for us. I think we can play better than that and credit to the lads as they kept going."
Jackson added he was delighted to see Eaves, the striker on loan from Bolton, score his first goal in 10 games.
"It's about time, isn't it?" said Jackson. "Credit to him and he needed that because he's a confidence player.
"He showed glimpses last week at Swindon and I'm made up for him because it wasn't easy playing against them."
Jackson, whose side remain in the relegation zone, now wants this point to be the start of a much-needed revival.
He added: "We've got to go to Sheffield United now next week and use that as some sort of springboard. We've got to improve on that again."
The goal from Eaves was the first time the Shrews had scored at the Greenhous Meadow in more than 10 hours of football.
