The Evri vs Royal Mail decision boils down to four trade-offs: cost, speed, letterbox delivery, and reliability perception. The calculator above runs a side-by-side comparison for any weight; this page covers when each wins.
At a glance: cost difference by weight
| Weight | Evri Standard | Royal Mail Tracked 48 (with C&D) | Evri saving |
|---|---|---|---|
| 500g | £2.99 | £3.75 | £0.76 |
| 1kg | £2.99 | £3.75 | £0.76 |
| 2kg | £3.49 | £4.70 | £1.21 |
| 5kg | £4.49 | £7.55 | £3.06 |
| 10kg | £6.99 | £11.35 | £4.36 |
| 15kg | £9.99 | £18.00 (estimate at upper bracket) | £8+ |
Evri wins decisively at higher weights. The percentage saving grows from ~20% at 1kg to ~40%+ at 5kg.
When Royal Mail is the right choice
Letterbox-fit items. Royal Mail’s Letter and Large Letter services are letterbox-deliverable. No signature, no missed-delivery slips, no redelivery hassle. For small flat items (CDs, paperbacks, vinyl, trading cards, prints), Royal Mail’s letter services often beat Evri on UX even when Evri Postable is slightly cheaper.
Speed-critical shipments. Tracked 48 is 2-3 days; Tracked 24 is 1-2 days. Evri’s fastest standard option is Next Day at premium pricing. For Vinted’s “buyer expects fast delivery” culture, Royal Mail’s middle-speed tier hits a sweet spot Evri Standard misses.
Higher-value items. Tracked 24/48 has marginally better tracking granularity and (subjectively) lower complaint rates. For items £50+, the small premium over Evri Standard often pays for itself in fewer disputes.
Customer expectations in certain categories. Collector communities, gift purchasers, and some demographics explicitly prefer Royal Mail. Listing in those categories with Royal Mail as the named carrier can reduce inquiry/complaint rates.
When Evri wins
Higher weights (2kg+). The cost gap widens significantly. A reseller shipping 200 parcels/year averaging 3kg saves £200-£400/year going Evri.
Bulk/volume shipping. For sellers shipping 50+ parcels/week, the per-parcel saving compounds. £1.50 average saving × 200 parcels/month = £300/month, £3,600/year.
Items where speed isn’t critical. Vintage clothing, books, low-priority items where the buyer accepts 5-7 day delivery in exchange for free or cheap shipping.
Budget-tier listings. Some Vinted/eBay sellers explicitly position on price (“free shipping included”) — Evri’s lower cost lets them maintain that pricing without margin destruction.
Reliability: what data actually shows
Public complaint data and customer satisfaction surveys consistently rank Royal Mail higher than Evri for missing/damaged parcels. The gap has narrowed since Evri’s 2022 rebrand and reliability investment, but it’s still measurable. National averages don’t apply to your local area though — driver quality varies enormously by postcode. Trustpilot and Reddit local-area threads are surprisingly useful here.
For most UK resellers shipping average-value items (£10-£50), the £1-£3 saving per parcel using Evri makes sense even with marginally higher complaint rates. For higher-value items or particularly complaint-sensitive categories, Royal Mail is worth the premium.
What this calculator doesn’t model
- International shipping — both carriers offer international services, not modelled here.
- DPD, UPS, FedEx — premium couriers for time-critical or specialty shipping, typically 2-3x the cost.
- Yodel — similar pricing/reliability to Evri, less common for consumer resellers.
- Pickup/collection fees — both carriers offer collection services (extra fee).
- Insurance/compensation differences — modelled tariffs include standard service compensation; high-value items need third-party insurance.
Putting it together
For most active UK resellers, the optimal mix is:
- Letterbox-fit items: Royal Mail Letter / Large Letter
- Sub-1kg parcels, budget: Evri Standard
- Sub-1kg parcels, speed-sensitive: Royal Mail Tracked 48
- 2kg+ parcels, budget: Evri Standard (significant savings)
- 2kg+ parcels, premium: Royal Mail Tracked 48
- High-value items (£100+): Royal Mail Tracked 24 or Special Delivery
