What is a soft opt-in?

Key Facts

  • A soft opt-in lets businesses contact former customers about similar services without fresh explicit consent per Dutch legal analysis.
  • The Netherlands' telemarketing soft opt-in expires 1 July 2026, but remains in place for email and SMS marketing according to ICTRecht.
  • Under the TCPA, there is no soft opt-in for marketing texts — prior express written consent is required per US SMS compliance guidance.
  • A February 2026 Fifth Circuit ruling permits oral TCPA consent, but only in Texas, Louisiana, and Mississippi per compliance experts.
  • Multi-channel email and SMS reactivation campaigns achieve 10–25% reactivation rates versus 2–6% for email-only efforts per practitioner data.
  • Reactivation leads can be generated at 67% lower cost than SEO or PPC campaigns per industry benchmarks.
  • A defensible consent record needs a timestamp, disclosure language, opt-in source, and campaign identifier per compliance experts.

Most business owners assume that if someone once handed over their phone number at the booking desk, that number is permission to reach out forever. It isn't. Consent rules for reactivation campaigns are jurisdiction-specific and channel-specific, and the gap between what feels right and what's legal is where expensive mistakes happen.

The concept that trips people up is the soft opt-in — an existing-customer exception that lets businesses contact current or former customers about similar products or services without fresh explicit consent. Under Dutch law, for example, this exception historically allowed companies to call existing or former customers for up to three years after their last purchase, provided the number was collected with notice and an opt-out was offered on each call, according to legal analysis from ICTRecht. Even there, the rules are tightening: from 1 July 2026, telemarketing in the Netherlands requires prior, voluntary, and specific consent — "No permission = no phone call" — while the soft opt-in remains in place for email and SMS marketing.

That split — softer treatment for some channels, stricter for others — is exactly what makes reactivation planning confusing. The rationale regulators give is that phone calls create pressure to say yes immediately, while email and SMS let recipients read on their own schedule with time to reflect.

Here's the critical part for US service businesses: there is no soft opt-in for marketing texts under the TCPA. Promotional messages — including win-back and reactivation campaigns — require prior express written consent: a signed or electronically signed agreement that clearly discloses the consumer will receive automated marketing texts and that consent isn't a condition of purchase, per this US SMS compliance guide. As one dormant-customer reactivation guide puts it, a past customer's phone number is not blanket permission for a marketing text.

The rules are also actively shifting, which makes assumptions dangerous:

  • The FCC's one-to-one consent rule was vacated by the Eleventh Circuit in January 2025, days before taking effect — leaving prior express written consent as the operative standard.
  • A February 2026 Fifth Circuit ruling held that the TCPA permits oral consent, but that applies only to Texas, Louisiana, and Mississippi — and compliance experts still advise collecting written consent as your baseline.
  • State mini-TCPA laws, like Virginia's amended Telephone Privacy Protection Act, layer additional obligations on top of federal rules.

The practical takeaway: before any reactivation outreach, you need to know what consent you actually captured, when, and through which channel. A defensible consent record includes a timestamp, the full disclosure language the customer saw, the opt-in source, and the phone number with a campaign or brand identifier. "If you cannot prove compliance, you are not compliant" — a standard CallMyCustomers applies to every campaign it runs, working only from lists of real customers with every message approved by the business owner first.

What a Soft Opt-In Actually Is — and Where It Applies

A soft opt-in is not blanket permission to contact anyone who has ever bought from you. It is a specific legal exception that allows businesses to reach out to existing or former customers about similar products or services without obtaining fresh explicit consent—provided the original interaction included clear notice and an easy way to opt out. This concept originates from European data protection frameworks, where it recognizes the reduced privacy intrusion when contacting someone with an established commercial relationship. As explained by ICTRecht, a Dutch legal consultancy, the soft opt-in previously permitted telemarketing outreach to past customers for up to three years after their last purchase, as long as the number was collected transparently and each call included an opt-out opportunity.

However, this exception is changing. In the Netherlands, the soft opt-in for telemarketing will expire on 1 July 2026, meaning businesses will need prior, voluntary, and specific consent to call consumers for commercial purposes—no permission will equal no phone call. Crucially, the same source confirms that for email and SMS marketing, the soft opt-in will remain in place, creating a regulatory split where digital channels retain more flexibility than telephone outreach. This distinction reflects concerns about the immediacy and pressure of live calls compared to the asynchronous nature of email and text, which allow recipients to review offers on their own schedule.

In the United States, the legal landscape operates differently. There is no recognized "soft opt-in" under the TCPA for marketing texts or calls. Instead, promotional messages—including win-back or reactivation campaigns—require prior express written consent. A past customer’s phone number alone does not constitute permission to send marketing texts, even if they previously engaged with your business. As noted in industry guidance, marketers must have a signed or electronically signed agreement that clearly discloses the consumer will receive automated marketing messages and that consent is not a condition of purchase. This requirement applies regardless of how recently the customer last interacted with the business.

Consent rules are also in flux. The FCC’s proposed one-to-one consent rule was vacated in January 2025, leaving prior express written consent as the federal standard. Meanwhile, a February 2026 Fifth Circuit ruling held that oral consent may suffice for automated telemarketing calls and texts—but only in Texas, Louisiana, and Mississippi. Experts advise treating this as a potential legal defense, not a reason to relax consent practices. Adding complexity, state-level mini-TCPA laws create a patchwork of obligations, meaning federal compliance alone may not be sufficient for national campaigns.

For businesses running reactivation efforts, this regulatory split has practical implications. Email remains the safest initial channel when consent status is uncertain, particularly given its stronger soft opt-in treatment in jurisdictions like the Netherlands and its lower regulatory risk under US TCPA interpretations. Honoring opt-outs immediately—through any reasonable method, not just STOP keywords—is not just compliance; it’s list hygiene that improves deliverability and trust. CallMyCustomers integrates these principles into every campaign, ensuring messages are approved by the client, opt-outs are honored in real time, and outreach aligns with both federal and state-level expectations. Reactivating known customers is far more cost-effective than cold acquisition—but only when consent documentation, channel rules, and opt-out mechanics are handled with precision.

Reactivating a known customer costs roughly one-fifth of acquiring a new one, making it a powerful second revenue engine for service businesses. Industry benchmarks show reactivation leads can be generated at 67% lower cost than SEO or PPC campaigns, but this advantage vanishes if compliance missteps trigger TCPA exposure. A defensible consent record isn’t just legal checkbox — it’s the foundation that protects reactivation ROI by proving prior express written consent was obtained for promotional outreach.

What makes a consent record defensible? It must include a timestamp of consent, the exact disclosure language presented to the customer, the specific channel or source where opt-in occurred (such as online booking or in-person service), and the phone number paired with a clear campaign or brand identifier. Compliance experts stress that without these elements, businesses cannot prove consent — and if you can’t prove compliance, you are not compliant. This level of detail transforms consent from a vague assumption into auditable infrastructure.

When consent status is unclear — such as with dormant customers whose last interaction predates current regulations — email remains the safest first move. Industry guidance notes that email allows consumers to review offers on their own schedule, reducing pressure compared to real-time channels like phone or SMS. Multi-channel sequences that layer email with SMS or voice achieve 10–25% reactivation rates, far outperforming email-only efforts at 2–6%, as shown in practitioner data. But these gains only hold when every channel adheres to its consent rules — especially texting, which under TCPA requires prior express written consent for promotional content regardless of prior relationship.

Honoring opt-outs immediately via any reasonable method isn’t a failure — it’s a feature of healthy list hygiene. Regulatory sources confirm consumers may opt out through any reasonable channel, not just STOP keywords, and treating unsubscribes as list cleanup improves deliverability and trust. For CallMyCustomers, this means every reactivation campaign runs only on verified customer lists, with optals honored in real time and all messaging pre-approved by the client. Compliance isn’t a constraint on reactivation — it’s the discipline that keeps the margin intact.

Running a Compliant Reactivation Campaign: Practical Steps

Running a compliant reactivation campaign starts long before the first message is sent. The most effective campaigns begin with an audit of consent records at the list review stage, ensuring every outreach effort rests on documented permission rather than assumption. This proactive step is especially critical in the US, where a past customer’s phone number does not constitute blanket permission for marketing texts under the TCPA — prior express written consent is required for promotional messages, including win-back or seasonal reminders.

Segmenting your list by recency — 30 days, 6 months, and 12+ months — allows for tailored messaging that aligns with both customer behavior and consent validity. Research shows that reactivation rates decline sharply beyond 12 months of inactivity, making timely outreach essential for maximizing response while minimizing compliance risk. For example, well-segmented dormant reactivation campaigns achieve open rates of 20–35%, and multi-channel approaches (email + SMS) yield reactivation rates of 10–25% compared to just 2–6% for email-only efforts.

Choosing a reason to reconnect that feels useful — such as a seasonal service reminder, a post-job thank-you, or a renewal notice — transforms outreach from pushy to helpful. Every script, offer, and message must be approved by the business owner before deployment, ensuring brand alignment and consent compliance. Outreach should run across approved channels, with calls handled by trained agents and texts/emails sent in the business’s name, all while respecting quiet hours (typically 8 a.m.–9 p.m. recipient local time) and honoring opt-outs immediately through any reasonable method, not just STOP keywords.

Replies must route seamlessly into the client’s existing booking process, turning engagement into revenue without manual handoffs. Treating compliance as infrastructure — embedding consent documentation, opt-out handling, and channel rules into the campaign workflow — protects ROI while building trust. CallMyCustomers’ free list review reveals exactly what your list can legally produce before any fee is incurred, turning compliance from a barrier into a competitive advantage. This approach ensures reactivation campaigns don’t just recover revenue — they reinforce permission-based relationships that last.

Frequently Asked Questions

What is a soft opt-in and how does it work for reactivation campaigns?
A soft opt-in is an existing-customer exception that allows businesses to contact former or current customers about similar products or services without fresh explicit consent, provided the original interaction included clear notice and an easy opt-out. It applies differently by jurisdiction and channel, such as remaining valid for email and SMS in the Netherlands after telemarketing rules change in 2026.
Can I use a past customer's phone number to send marketing texts in the US without getting new consent?
No, under the TCPA, a past customer's phone number alone is not permission to send marketing texts—promotional messages require prior express written consent, regardless of prior relationship. This includes win-back and reactivation campaigns.
Is oral consent enough for sending marketing texts under US federal law?
While a February 2026 Fifth Circuit ruling held that oral consent may suffice for automated telemarketing calls and texts, this applies only to Texas, Louisiana, and Mississippi. Compliance experts still advise collecting written consent as a baseline for national campaigns.
What makes a consent record defensible for reactivation outreach?
A defensible consent record includes a timestamp of consent, the exact disclosure language presented, the specific opt-in source (e.g., online booking), and the phone number paired with a campaign or brand identifier. Without these, you cannot prove compliance—and if you can't prove it, you are not compliant.
Why is email often recommended as the safest first channel for reactivation when consent status is unclear?
Email is recommended because it allows recipients to review offers on their own schedule, reducing pressure compared to real-time channels like phone or SMS. It also benefits from softer consent treatment in jurisdictions like the Netherlands and carries lower regulatory risk under US TCPA interpretations for reactivation.
Do I have to honor opt-outs only through STOP keywords, or can customers use other methods?
Consumers may opt out through any reasonable method, not just STOP keywords—honoring opt-outs immediately via any reasonable channel is required and improves list hygiene, deliverability, and trust.

Your Customer List Is an Asset — If You Treat It Like One

The soft opt-in isn't a loophole — it's a reminder that consent is contextual, channel-specific, and time-sensitive. In the US, a past customer's phone number isn't permission to text; prior express written consent is the standard, and the rules keep shifting. Email remains the safer first move when consent records are thin, and honoring opt-outs through any reasonable method isn't just compliance — it's list hygiene that protects deliverability and trust. Reactivating known customers costs a fraction of cold acquisition and multi-channel sequences can hit 10–25% reactivation rates, but only when consent documentation, channel rules, and opt-out mechanics are handled with precision. That's the infrastructure CallMyCustomers builds into every campaign: verified customer lists, owner-approved messaging, real-time opt-out handling, and outreach that aligns with both federal and state expectations. Your next booked customer already knows your business. The question is whether your consent records can prove you're allowed to reach them.
