What is Opt-in?
Explicit permission from a person to be contacted: the consent, usually a checkbox or form submit, that makes marketing to them legitimate.
What is Opt-in?
An opt-in is a person's recorded agreement to hear from you: ticking a consent box, submitting a form that states what they will receive, or confirming a subscription. Single opt-in takes the form submission as consent; double opt-in adds a confirmation email, trading a little list growth for a list that is provably real and engaged.
Opt-in is not just etiquette; in Nigeria it is the law. The NDPR (and the NDPA that built on it) requires consent for using personal data for marketing, and GDPR applies the same standard to European contacts. A recorded opt-in, who consented, when, to what, is the difference between marketing and spam, legally and practically.
Why it matters
Permission is the asset your whole email programme stands on. Opted-in lists get opened, clicked and delivered; scraped and purchased lists get spam complaints, which damage deliverability for every email you send, including receipts and reminders. Consent records also turn a regulatory audit from a panic into a lookup.
How it works in Medivot
Consent is built into Medivot's capture points: webinar registration pages carry a marketing opt-in in your own words, landing page forms support consent checkboxes, and consents are recorded in a ledger with their source, supporting NDPR and GDPR obligations including data subject requests. Contacts without marketing consent simply never receive campaigns.
Frequently asked questions
What is the difference between single and double opt-in?
Single opt-in subscribes someone on form submit; double opt-in sends a confirmation email they must click first. Double opt-in grows lists slightly slower but produces provable consent and filters out typos and fake addresses, which protects deliverability.
Do I need consent to email customers in Nigeria?
For marketing, yes: the NDPR expects consent or another lawful basis, and marketing to your own customers still requires that they can opt out and that you honour it. Transactional messages like receipts and booking confirmations are different from campaigns and do not need marketing consent.
