DKIM adds a digital signature to your outgoing emails so receiving servers can verify they genuinely came from your domain. It significantly improves email deliverability and protects your domain from spoofing.
SPF (Sender Policy Framework) is a DNS record that lists which mail servers are allowed to send email on behalf of your domain. Without SPF, your emails are more likely to land in spam folders.
DMARC tells receiving servers what to do when emails fail SPF or DKIM checks — monitor, quarantine or reject. It also sends you reports about who is sending email from your domain.
47% of recipients decide to open an email based on the subject line alone. Testing your subject lines before sending can significantly improve your open rates and overall campaign performance.
Using a professional email address like name@yourdomain.com instead of a free Gmail account builds trust with customers and improves email deliverability for your business communications.
Keep subject lines under 50 characters, use numbers, create curiosity, personalise with names, and avoid spam words like FREE!!!, CLICK HERE, or BUY NOW to maximise open rates.
A professional signature builds trust, reinforces your brand on every email you send, and makes it easy for recipients to find your contact details and social profiles instantly.
MX (Mail Exchange) records tell the internet which servers handle email for a domain. Checking MX records helps you confirm your email setup is correct or see which provider another company uses.
Gmail treats dots in the username as invisible — john.doe@gmail.com and johndoe@gmail.com are the same inbox. Useful for organising signups or claiming multiple free trials, but always follow each service's terms of use.
