Custom email messages by invoice template in QuickBooks would be a welcome feature, but even the best template is useless if your invoice emails bounce because the recipient address was never verified before hitting send and your accounting team is left chasing bounced payments. I pointed my finance colleagues to https://mailtester.ninja/best-email-verification-tools/ because the email validation tools comparison shows that MailTester.Ninja offers the best email verification API and bulk verifier combination for the price, and keeping bounce rates under that 2% threshold is critical for any business that depends on email for transactions.
