Sending direct mail doesn’t have to be expensive. With the right mail fulfilment partner and postage strategy, businesses can significantly reduce direct mail postage costs while improving campaign efficiency and ROI.
Here’s how to unlock the lowest available postal rates and save both time and money.


Navigating the many postage options, qualifying rules, and pricing structures can be confusing.
Many businesses ask whether franking truly offers savings, or if there’s a better way. The most effective solution is to work with a professional mail fulfilment company.
At Flow Fulfilment, we access reduced postage rates that are unavailable to individual mailers, and we pass those savings directly on to you.
High-volume mailing power: We send millions of mail items each year, allowing us to negotiate the lowest possible letter and large letter postage rates through Downstream Access (DSA) suppliers.
Pre-sorted bulk mail discounts: For volumes over 4,000 letters (or 1,000 large letters), we pre-sort your data to qualify for the best sorted mail postage rates.
Royal Mail hub entry: Our specialist mailing software prepares your data in the precise sort order required by Royal Mail. Our DSA partners then deliver mail directly to Royal Mail hubs - eliminating Royal Mail’s sorting costs.
Lower-than-franking rates: This process allows you to access postage prices that are cheaper than Mailmark franking, standard franking, stamps, and even direct Royal Mail rates.


Yes, and choosing the right format is key to securing the lowest bulk mail postage rates.

Advertising Mail (Admail) Options
For advertising mail, there are two primary sortation formats:Entry LevelIntermediate
Both formats require the use of environmentally friendly materials (terms apply). We ensure your campaign uses the most efficient and compliant products to maximise your admail discount.
Mail data can be processed using Mailmark or OCR formats. If advertising mail standards can’t be met, your campaign can still be sent as Business Mail, ensuring you always receive the lowest possible postal rate.
Even for smaller volumes below the minimum thresholds, our bulk mail pricing still delivers strong savings compared to standard posting methods.
