Bank of America's Secret Mailer: 3% Cash Back Everywhere for a Year

If you've been ignoring that envelope from Bank of America, you might want to open it. Some folks are getting a pretty sweet targeted offer on the Unlimited Cash Rewards card: double the usual cash back rate for an entire year. No sign-up bonus, but the earning potential could be way better than a one-time bonus.

What's in the Mailer?

Bank of America is sending out physical mailers to select customers with a different spin on their usual welcome offer. Instead of the standard $250 bonus after spending a certain amount, this one gives you 3% cash back on every purchase for the first year. That's double the card's normal 1.5% rate.

The mailer also mentions a 0% intro APR on purchases for 15 months. So if you're planning a big purchase or want to carry a balance for a while, that's a nice extra.

The offer is valid through September 29, 2026, so if you got the mailer, don't sit on it forever.

• 3% cash back on all purchases for 12 months
• 0% APR on purchases for 15 months
• No annual fee
• Targeted – not available to everyone

Why This Could Be a Better Deal Than a Sign-Up Bonus

At first glance, skipping a $250 bonus might seem like a downgrade. But let's run the numbers. If you spend, say, $2,000 a month on your credit card, that's $24,000 over the year. At 3% cash back, you'd earn $720. That's nearly three times the standard bonus.

Even if you spend less – say $1,000 a month – you'd still earn $360, which beats the $250 bonus. And you don't have to hit a minimum spend requirement to get it. The cash back just rolls in automatically.

For people who use their card for everything, this could be a no-brainer. The only catch is that you have to be targeted. There's no public link to get this offer, so if you didn't get the mailer, you're out of luck.

Preferred Rewards Members Can Stack Even More

If you have a Bank of America checking account or Merrill investment account, you might be part of the Preferred Rewards program. That gives you a boost on your cash back – up to 75% more depending on your balance tier.

With this targeted offer, the math gets wild. The base rate is 3%, but Preferred Rewards members get an extra 0.5% to 1.12% on top of that. The highest tier (Platinum Honors, with $100k+ in combined balances) would earn 4.12% cash back on everything. That's insane for a no-category card.

Just remember: the bonus rate only lasts for the first year. After that, you're back to the standard 1.5% (or 2.62% if you're a Platinum Honors member). So make the most of that first year.

• Preferred Rewards tiers: Gold (0.5% boost), Platinum (0.75%), Platinum Honors (1.12%)
• With the targeted offer, Platinum Honors members earn 4.12% cash back on all purchases
• Boost applies to the base 3% rate, not the standard 1.5%

Things to Watch Out For

First, this is a targeted offer. If you didn't get the mailer, don't try to apply for the card and expect this deal – you'll likely get the standard $250 bonus instead. That's still a good offer, but it's not the same.

Second, the 3% rate is only for the first 12 months. After that, you're back to the regular 1.5% (or whatever your Preferred Rewards tier gives you). Set a reminder to re-evaluate your card strategy before the year ends.

Third, the 0% APR period is 15 months, which is longer than the 3% cash back period. That's fine – just don't confuse the two timelines.

Finally, make sure you understand the Preferred Rewards boost. It's based on your combined balances across Bank of America and Merrill. If you're close to a higher tier, consider moving some money over to get the bigger boost.

Bottom Line

• If you got the targeted mailer, this offer beats the standard $250 bonus for most spenders.
• Preferred Rewards members can earn up to 4.12% cash back on everything for a year – a rare deal.
• The 0% APR for 15 months is a nice bonus for those planning large purchases.
• Don't apply without the mailer – you'll get the standard offer instead.
