Email Marketing: Lists, Automation and Consent Under UK PECR
How to gather consent properly for an email list, what UK PECR actually requires, and how to build automation around it.

Short answer
In email marketing, what decides the outcome is not list size but whether every address on the list actually consented; a campaign sent without consent carries legal risk and tends to get flagged as spam, which then hurts future sends too. In the UK, this is governed by PECR, the Privacy and Electronic Communications Regulations; in Turkey the same job is done through a national consent register called İYS.
By 2026, large providers such as Gmail and Yahoo have made authentication (SPF, DKIM, DMARC) and one-click unsubscribe mandatory for senders sending above a certain daily volume; sends that do not meet these rules get delayed, or never arrive at all.
This piece covers gathering consent properly, what PECR actually asks for, and what a properly built automation set-up looks like.
A list without consent is not a list
Sending direct marketing by electronic mail to individuals in the UK requires either consent, or meeting all the conditions of the soft opt-in exception. Soft opt-in covers cases where the recipient has previously bought something from you and has not opted out of receiving marketing about similar products or services.
For an umrah and hajj tour operator, launching a campaign on a purchased email list can look like reaching a wide audience quickly, but since that list was never built on genuine consent it carries legal risk and tends to open at a very low rate; a recipient who never asked for the email usually deletes it unread.
What PECR actually requires
PECR requires that direct marketing sent to individuals by electronic mail has either consent or meets all the conditions of the soft opt-in exception. Electronic mail is defined broadly here: email, text message, voicemail, and direct messaging on social media all fall under it.
Instigating a third party to send on your behalf also brings PECR responsibility onto you, if you encouraged or asked for that send to happen.
How to gather consent properly
The soundest way to gather consent is a form that says plainly what the visitor is signing up for; a concrete promise such as 'get weekly product updates and offer announcements' rather than a vague 'sign up to our newsletter' improves both the quality of consent and lowers the risk of future complaints.
- The consent tick box on a form should never be pre-ticked
- What kind of content will be sent (campaign, newsletter, reminder) should be stated clearly
- In Turkey, consent should be logged with İYS, ideally at the same time as the form is submitted
- Every email needs a one-click unsubscribe link
How to set up the automation
Automation makes it easier to send well-timed email to a consenting list: a welcome email when a form is submitted, a thank-you and related product suggestion after a purchase, and similar triggered sequences. The value of automation shows up more in these well-timed sequences than in one-off bulk sends.
For a spa and fitness centre, an automatic reminder email sent a week before a membership renewal date worked far more consistently than a manually tracked process; automation solved a timing problem here, not a sales one.
Why deliverability rules matter
Gmail requires authentication (SPF, DKIM, DMARC) and one-click unsubscribe for senders sending above a certain volume of bulk mail per day; sends that fail to meet these get rejected or dropped into spam. Even for a small business, getting these technical settings right decides whether an email actually reaches the inbox at all.
Why segmentation lowers unsubscribe rates
Sending the same email to an entire list tends to push recipients who get irrelevant content towards unsubscribing, or marking the email as spam. Segmentation means splitting the list by purchase history or interest and sending each group content that is actually relevant to them.
For a generator manufacturer, industrial customers and home users were kept on one list receiving the same content; once split into separate segments with content matched to each group's interest, open rate rose noticeably and unsubscribe count fell.
What to look for when choosing an automation tool
Choosing an automation tool should be driven by the complexity of the sequence being built, not by list size; a simple welcome sequence does not need a complex platform.
For a generator manufacturer, the need was only a three-step sequence, welcome, product information, quote reminder, so a simple tool was enough; moving to an unnecessarily complex platform would have raised both cost and the learning curve.
What actually matters when choosing a tool is compliance features such as İYS integration and one-click unsubscribe support; without those, even the most advanced tool still carries risk.
Switching tools later means migrating the list and its automation history, so it is not a decision to make often; getting the first choice right removes that migration burden down the line.
Email marketing comes down to working with a consenting, well-timed list rather than a large one. Once İYS registration, PECR compliance and technical deliverability settings are correctly in place, automation quietly does the rest of the work. If you would like your own list reviewed for consent and automation, a discovery call is a good place to start.
FAQ
Can a purchased email list be used?
Without meeting PECR's consent requirement in the UK, or İYS registration in Turkey, this kind of list carries legal risk and usually opens at a very low rate.
Is İYS registration mandatory in Turkey?
Yes, for any business sending commercial electronic messages (email, SMS, calls), İYS registration is required under Ticaret Bakanlığı regulation.
What is soft opt-in?
It is the UK exception that allows email to be sent without explicit consent where the recipient has previously bought from you and has not opted out of marketing for similar products.
Do I need a large list before setting up automation?
No, automation's value comes from the right trigger and timing rather than list size; it works well on a small list too.
