How this guide was prepared. Last updated October 2026. It draws on Brandmovers' experience designing loyalty programs and member communications for consumer and B2B brands. It also draws on FTC and Gmail guidance, Apple's documentation and a peer-reviewed study, listed under Sources. |
Loyalty program emails are messages sent to program members about their place in the program: points, available rewards, tier progress, benefits and program changes. Most are triggered by a member's activity or a date rather than sent to the whole list, which can make them more relevant than general marketing email.
This guide covers eight loyalty program emails that keep existing members engaged after they join, with what triggers each one, what to include, a short example and what to measure. It then covers the email rules that apply, how often to send and how to judge results. Welcome emails for new members are covered in the companion guide to onboarding emails for new loyalty program members.

A loyalty program should send emails tied to member milestones: reward available, near-tier, tier reached, anniversary, benefit reminder, points expiring, win-back and program change notices.
Each email below answers a question a member might not think to ask: what can I get now, how close am I, what do I have, what am I about to lose, and what has changed. Together they cover the member's time in the program after onboarding. Not every program needs all eight; a program without tiers skips two, and a program whose points do not expire skips one. Start with the emails tied to the behavior you most want to change, such as redemption or repeat purchase, and add others once the first ones are measured. In B2B programs, such as dealer or contractor incentives, the same emails apply, but triggers usually follow claims, sales periods or quarterly targets rather than individual purchases. A small program without automated triggers can start with one monthly statement that shows the balance, rewards within reach and points expiring soon, then add triggered emails as it grows. Whatever the size, put key facts such as the balance and expiration date in live text rather than only in images, and add alt text, so every member can read them. The example lines below are illustrative wording, not copy from a specific program.
A reward available email tells members what their current points balance can buy right now, prompting redemption with options matched to their balance and past purchases.
Match suggested rewards to what each member buys or has redeemed before, using purchase and redemption history. Avoid featuring rewards far beyond the member's balance: an email about an unreachable reward gives the member nothing to act on now.
A next-tier reminder tells members how close they are to the next tier and what it unlocks, sent only when the remaining gap is realistic for their normal spending.
Research on goal progress is consistent with this timing: in a study of a café rewards program, Kivetz, Urminsky and Zheng found that members "purchase coffee more frequently the closer they are to earning a free coffee" (Journal of Marketing Research, 2006). The study measured purchases near a goal, not reminder emails, but the same logic suggests sending tier reminders only when the goal is close. If a member is $500 from the next tier and usually spends $20 per order, a reminder asks too much; wait until the gap is a purchase or two. The guide to designing a tiered rewards program covers how to set thresholds that make these reminders work.
A tier achieved email congratulates members on reaching a new tier and explains exactly what they now receive and how long the status lasts, so they use the new benefits.
Members who do not know their benefits cannot use them, and a benefit that goes unused is unlikely to give a member a reason to stay. Follow up with a reminder if a key benefit has not been used within the first month.
Anniversary and birthday emails recognize a date that matters to the member, such as the day they joined or their birthday, usually with a small reward or bonus points.
Collect birthdays only with a clear reason and let members skip the field, and in age-restricted categories such as alcohol, tobacco or cannabis, check what state rules allow before attaching a reward; a program anniversary works for every member without extra data. Brand anniversaries, such as the program's launch date, can also give all members a reason to engage at once.
A benefit reminder tells members about program perks beyond points, such as free shipping, early access or samples, especially members whose activity shows they are not using them.
Benefit usage data also shows which perks members value. A benefit few members use after reminders may need redesigning rather than more emails.
A points expiring reminder warns members before their points or rewards expire, giving them time and options to redeem, which can reduce complaints and give members a reason to return.
Points that expire without warning can frustrate members. Clear reminders cost little and protect trust; the guide to point breakage covers why unredeemed points matter to the business and how expiration rules vary by state. For time-sensitive notices like this one, an SMS or app notification can reach members who rarely open email; check each channel's consent requirements before adding it.
A win-back email reaches members whose activity has dropped, before they leave, with a reason to return that matches their history, such as a reward they are close to.
Base the trigger on each member's own cycle rather than one rule for everyone: a member who buys weekly is lapsing after a month, while a seasonal buyer is not. Repeated bonuses can teach members to wait for an offer, so test whether a reminder alone works before adding one. A win-back email that promotes an offer is commercial email, so do not send it to members who have opted out of marketing email. The guide to re-engaging dormant loyalty members covers win-back in more detail.
A program change notice tells members in advance about changes to earning, rewards, tiers or terms, explaining what changes, when, and what happens to points they already hold.
Members who discover a change on their own, especially a cut in point values, can feel misled in a way that a clear advance notice avoids. Give enough notice for members to act, and at least any notice period your program terms promise, and make the email easy to find later.

Promotional loyalty emails must follow the CAN-SPAM Act, and large senders must meet inbox providers' rules such as Gmail's one-click unsubscribe; some balance statements can count as transactional or relationship messages.
The CAN-SPAM Act covers any email whose primary purpose is "the commercial advertisement or promotion of a commercial product or service," according to the FTC's compliance guide. Commercial emails must use accurate header information, non-deceptive subject lines, identify the message as an ad, include a valid physical postal address and explain how to opt out, and "You must honor a recipient's opt-out request within 10 business days" (FTC). This applies to B2B loyalty programs too: "The law makes no exception for business-to-business email."
Some loyalty emails may be transactional or relationship messages, which are "exempt from most provisions of the CAN-SPAM Act" as long as they do not contain false or misleading routing information. The FTC lists messages that provide "regular, periodic account balance information," report changes in "the terms or features of a membership, subscription, account," or notify the recipient "of a change in their standing" in that relationship. But it adds: "Keep in mind that the law views these categories narrowly," and warns against assuming that every message to people with an ongoing relationship qualifies, "including subscribers or recipients who participate in a membership program." When an email mixes both kinds of content, the FTC treats it as commercial if a recipient reading the subject line would likely see it as an advertisement, or if the transactional content does not appear mainly at the beginning. The simplest approach is to treat mixed emails as commercial and include the required elements.
Inbox providers add their own rules. Gmail requires senders of more than 5,000 messages a day to Gmail accounts to meet added rules, including: "Marketing messages and subscribed messages must support one-click unsubscribe, and include a clearly visible unsubscribe link in the message body." Gmail requires all senders to keep spam rates reported in Postmaster Tools below 0.3%, and its spam rate guidance adds: "Keep spam rates reported in Postmaster Tools below 0.10% and avoid ever reaching a spam rate of 0.30% or higher." It also recommends: "Always give recipients an easy way to unsubscribe from your messages" (Gmail Help). Because purely transactional or relationship messages are exempt from most CAN-SPAM provisions, members who opt out of marketing email can still receive genuine account messages, such as a plain balance statement, so keep the two lists separate. This is general information, not legal advice.
Send loyalty emails when a member's activity or a date makes them relevant, cap the total each member receives, and let members choose which types they get.
Triggered emails are spread out by nature, since each member hits thresholds at different times, but several triggers can fire in the same week. Set a cap on how many loyalty emails one member receives in a period, decide which emails take priority (a points expiring notice usually outranks a benefit reminder), and suppress promotional emails to members with an open service complaint. A preference center that lets members choose emails by type, such as statements, offers and program news, gives members an alternative to unsubscribing from everything; Gmail's guidelines also suggest letting recipients unsubscribe from lists individually: "Let them unsubscribe from lists individually, or all lists at once" (Gmail Help). Watch unsubscribe and spam complaint rates by email type; a rise after a new email suggests it is unwelcome.
Measure loyalty emails by the action they are meant to prompt, such as redemption, tier attainment or a return purchase, compared with a holdout group, not by open rates.
Open rates have become unreliable. Apple's Mail Privacy Protection, for example, "prevents senders from seeing if you've opened the email message they sent you" (Apple), so opens for many members are not a true signal. Clicks are more reliable, since Apple notes that "Mail Privacy Protection does not extend to links or email attachments," but they are still not the goal. For each promotional triggered email, hold back a small, random share of eligible members and compare their redemptions, purchases or tier progress with members who received it. That shows what the email adds beyond what members would have done anyway, which is the number that justifies sending it. Do not hold back notices members rely on, such as program changes or expiring points; test their timing or wording instead. In a small program, a holdout may be too small to show a reliable difference, so combine results over several months before drawing conclusions.
The emails that keep loyalty members engaged are the ones tied to their own progress: a reward within reach, a tier nearly reached, a benefit unused, points about to expire, a change on the way. Make each one specific to the member's balance and history, follow CAN-SPAM and inbox provider rules, cap frequency, and measure each email by the action it prompts against a holdout group. Which email in your program would members miss if it stopped?
