DBS is starting its annual MaximIsa marketing drive following its successful campaign last year, which pulled in £51m of business for its members.
Last year, more than 7,000 people took out Isas based on recommendations by DBS and the company is hoping to generate a similar response this season from its campaign costing £10,000.
The network is distributing 230,000 marketing packs containing letters and brochures listing its Magnificent Seven Isa recommendations covering a range of sectors.
The packs will initially be sent to DBS members so they can forward them on to clients.
The packs advise on the best Isas and offer discounts to customers on most recommended products.
The Isa recommendations are put together from an analysis of 2,000 funds by investment manager Neil Liver- sidge. He breaks these down into seven sectors to recommend the Magnificent Seven.
This year's recommendations are the Aberdeen fixed interest, Henderson global technology, Norwich Union UK growth, SG Asset Management European, Fidelity Weatherbuilder and Capel Cure Sharp ethical funds.
