Looking for Custom SMTP Providers Based in the UK – Recommendations Needed

I've been using https://rocketsmtp.io for my email marketing campaigns, and they've been great. They provide custom-made SMTPs tailored to each use case, which has really helped with my deliverability. However, they're based in the US, and I'm looking for a similar solution based in the UK.

Does anyone know of any reliable SMTP providers in the UK that offer custom-made SMTP services? Any recommendations would be greatly appreciated!

check out SMTP2GO and MailJet. Both are known for reliable SMTP services and have a strong presence in the UK.

MessageBird, Amazon SES, Sendinblue (Brevo), and SocketLabs - you can look at them.

do they have any uk based servers or is that the main reason you're looking to switch to a uk provider?
