Email going into Gmail Spam Folder

Please check your emails (both body and signature) for spammy content e.g. lots of exclamation marks; "must read"; attention-getting, large and/or gaudy coloured text; text the same colour as the background; tiny text; [almost] zero height images; links hidden under text, images or links with a different URL; etc. All or any of these may mark you as a spammer at Google. If all or most of your emails to Gmail accounts are being classified as spam at the Gmail end, or Google are blocking your domain, you will need to comply with the Bulk Sender's Guidelines at https://support.google.com/mail/answer/81126?hl=en&vid=1-635789122382665739-3305764358
