# GDPR Compliance for Email Marketing with AcelleMail

> GDPR governs how you process EU residents' personal data — and email addresses are personal data. This guide walks the five obligations that touch email marketing (consent, access, erasure, portability, processor agreements) and shows the AcelleMail UI for each.

## What this is for

The General Data Protection Regulation (GDPR) applies to any business that processes personal data of EU or UK residents — **regardless of where the business is located**. An email address is personal data. Sending marketing email to an EU recipient = processing personal data = GDPR applies.

The non-negotiables for email marketing are five: lawful basis for processing, right of access, right to erasure, right to portability, and a data-processing agreement with every third-party processor in the chain. This guide walks each one with the AcelleMail UI path.

## 1. Lawful basis (Article 6) — consent

For marketing email, the only practical lawful basis is **explicit consent**. The legal bar is:

- **Freely given** — not bundled with terms of service, not a condition of purchase
- **Specific** — they consented to marketing email, not "communications"
- **Informed** — they knew who they were consenting to and what they'd receive
- **Unambiguous** — a clear affirmative action; **pre-ticked boxes do not count**

In AcelleMail:

1. Open **Lists → [your list] → Edit** → **Subscription settings**
2. Turn ON **Double opt-in** — this produces a server-side timestamped confirmation log for every subscriber, the strongest form of consent record
3. In your signup form (**Forms → [your form] → Edit**), add an **unchecked** consent checkbox with explicit text — "I agree to receive marketing emails from [Company]. I can unsubscribe at any time." — linked to your privacy policy

The double opt-in confirmation timestamp is your audit trail. See [Double Opt-In vs Single Opt-In](https://acellesend.com/kb/articles/double-opt-in-vs-single-opt-in-which-to-choose) for the full setup.

## 2. Right of access (Article 15)

A subscriber can request all data you hold on them, free of charge, within one month.

In AcelleMail:

1. Open **Lists → [their list] → Subscribers**
2. Search for their email
3. Open the subscriber detail page — the profile shows email, MERGE fields (name, company, custom fields), subscription date, source list, and engagement history (opens / clicks / bounces)
4. From the subscriber's action menu, export the profile as CSV

If they're on multiple lists, repeat per list — or use **Search → Subscribers** to find every occurrence at once.

## 3. Right to erasure / "right to be forgotten" (Article 17)

The subscriber asks to be removed; you have one month to comply and must purge:

- The subscriber row from every list they're on
- All custom field data tied to them
- (Where possible) engagement history

In AcelleMail:

1. **Search → Subscribers** to find every occurrence of the email
2. Open each occurrence and click **Delete** — confirm
3. Subsequent campaign sends will not be able to target that email; AcelleMail's deduplication also prevents re-import as a "live" subscriber if they later try to re-subscribe via the same form (they'll need a fresh signup with a new confirmation).

Note: GDPR does *not* require you to delete from immutable system logs (e.g. webserver access logs, bounce-handler logs). Mainline subscriber records and your marketing CRM are what's in scope.

## 4. Right to portability (Article 20)

They get their data in a "structured, commonly used, machine-readable format" — CSV satisfies this. The Article 15 export above is sufficient for portability requests too.

## 5. Data Processing Agreement (Article 28)

If you use a third-party sending provider — Amazon SES, SendGrid, Mailgun, Postmark, SparkPost — that provider is a **data processor** and you must have a signed DPA with them. All the major SMTP providers publish their DPA online; sign once, retain a copy.

If you use AcelleMail **self-hosted** with your own SMTP and your own server, AcelleMail is not a processor of your subscriber data — your server is. You only need DPAs with services that touch the data downstream (e.g. your hosting provider, your bounce-handler IMAP host).

## The self-hosted advantage

GDPR has a "data residency" preference: keep EU residents' data inside the EU when practical. With AcelleMail self-hosted, you choose your server — put it in Frankfurt, Dublin, or Paris and you've solved data residency for free. SaaS competitors that run from US-only infrastructure complicate this; you don't have that complication.

## Common issues

| What you see | What to do |
|---|---|
| Pre-ticked consent checkbox on legacy signup form | Un-tick it. Re-permission anyone collected through it via a confirmation campaign. |
| Subscriber on 4 lists asks to be deleted; you delete from one and they keep getting email | Use **Search → Subscribers** (global) to find every occurrence before clicking delete. |
| Lawful-basis question on cold B2B outreach | "Legitimate interest" basis is debated for B2B; the safest read is to still use explicit opt-in. ICO (UK) guidance: B2B individual addresses still attract PECR / GDPR. |
| You're not sure whether your SMTP provider has a DPA | Their compliance/legal page will publish it. Amazon SES, SendGrid, Mailgun, Postmark all have public DPAs you sign electronically. |

## What to do after

1. Audit every signup form for un-pre-ticked consent + explicit text + privacy link.
2. Turn on **double opt-in** for any list that collects EU/UK residents.
3. If you use a third-party SMTP, sign their DPA today.
4. If you don't know where your server is hosted geographically — find out. EU residency is a feature, US-only is a friction point.
